Deleting map in Internal Memory.

 

I finally purchased a life time update for my Nuvi 765t. I downloaded the update to the internal memory and a 8 GB. memory card. Now I wanted to install the large JCV file on to memory of the Nuvi but found that I don't have enough memory. I want to use the card but how can I delete the map from the Nuvi?
Thank you.

Update

I think all you need to do is make a folder on your SD card in the Garmin folder and name the new folder JCV and then copy the JCV file into that folder.

I think also rather than deleting the old JCV file in your GPS, just add a symbol such as this % as the first part of the name of the file. This way if the new larger file does not work for you you can always revert back to the original file.

No need to do anything.

You automatically get the large JCV file with the map download on the 7x5 series. So there is no need to install a different JCV file ... you already have the large full coverage file.

If I interpret your post correctly, I think you installed the map to the internal memory of your 765T. So my guess is that your SD card is still mostly unused. If you really want the map on the SD, there are a couple of ways to do it. But since the full map still fits in internal memory on a 7x5 nuvi, why go through the grief of moving it to SD card?

Yes,

I have the map on both the SD card and the unit. Because the memory in the unit is getting low I would like to remove the map from it and use the SD card instead.

Well,

First, do yourself a BIG favor and make a backup of your nuvi before you do this.

The map files are in the \Garmin folder. There are 4 files: gmapprom.img, gmapprom.gma, gmapprom.unl, and gmap3d.img. The JCV file is in folder \Garmin\JCV and is named D3060070A.JCV.

If you are absolutely sure that all these files are also on SD, you can simply delete the files from the internal storage. Note that if the map files are correctly installed on SD, the 3 main map files on SD are named gmapsupp.* instead of gmapprom.*. The 3D and JCV files on SD have the same names that they do on internal storage.

There is one additional map file in internal storage. It is named GMAPTZ.IMG. This is the time zone map and it must remain in internal storage. It will not be loaded if it is moved to SD card.

You say you have the maps installed in both locations. Just to be sure, what method did you use to install the maps to SD?

I used the .

Garmin Lifetime Updater.

GPSmap76Cx handheld, Nuvi 2557LMT, Nuvfi 2598LMTHD

Be careful!

As far as I know, on the 7x5 series, the Lifetime Updater does not have an option to install the map to SD card. I could be wrong since I don't use that program for map updates. But it seems unlikely to me that Lifetime Map Updater would install the maps to both internal storage and SD. It would prompt you for the target location and install to one or the other, but not both.

I can't emphasize it enough. Make sure you know what you are doing before you start deleting things.

Files.

In the internal memory the files gmap3d and gmapprom have an extension "sum". The GMPTZ.IMG file I don't see at all. All the files you mentioned are not on the SD card. Obviously something went wrong.
Can I clean out the internal memory and start over and forget about the SD card?

--
GPSmap76Cx handheld, Nuvi 2557LMT, Nuvfi 2598LMTHD

No need to clean anything out.

There is really no need to clean anything out. The Map Update Installer will take care of removing the old files. Many users have had problems with the Lifetime Map Updater. I would suggest you use the manual installation method instead. To use the manual Method, connect your device, log on to your my.Garmin.com account, click on MyMaps, then click the "Download" button next to the current map. This will take you to a screen that says "Download Map Installer" or something similar. Click that and select "Run". Then follow the prompts to complete the map install. I am pretty sure this will install in internal storage and will give you the full coverage JCV file. I don't recall seeing an option to install to SD when I installed the map on my 755T.

Incidentally, the .SUM files are checksum files from running diagnostics. Any .SUM files you see can be safely deleted.

If you do want to do some cleanup on you nuvi, unused (non-English) voice files are something that is safe to delete. You will find these files in the \Garmin\Voice folder. The English files will be easy to recognize by the file names. The files for other languages you don't use can be deleted.

The other place you can delete non-English files is in the \Garmin\Help folder. Here you will see a folder for each language. Keep the American_English and British_English, but delete the other folders for languages you don't use.

Hope this helps.

Herb, listen to alandb since we all agree with alandb almost always wink

Make a backup of your nuvi

Reinstall your 2013.20 map from myGarmin since your installation apparently did not succeed

I agree with alandb that Garmin won't let you simultaneously install a map to the internal nuvi storage AND to an SD card

From Garmin's faq:

https://support.garmin.com/support/searchSupport/case.faces?...

it appears that the nuvi 7x5 series does allow for loading maps to SD card, which would include the appropriate JCV file, etc. If you're not seeing the window giving you the SD card installation option, it may be that Garmin knows your nuvi can handle the full North America map update internally. Should future updates become too large for your internal storage, the Garmin faq suggests you will be given the option of a full map update to SD.

Good luck with your reinstallation using the manual (not LifeTime) update procedure. I believe you need to log into myGarmin with your nuvi connected, then go to myMaps to be given the option to reinstall a map that Garmin thinks it's already installed to your unit (the one that apparently is missing some files).

Plz report back with questions or a declaration of success.

.sum files

The .sum files are checksums and are tiny files and essentially can be ignored by us.

In addition to the time zone file mentioned above, your nuvi should have the files indicated by alan:

gmapprom files are the City Navigator files (with the .img file being enormous)

gmapbmap files are the nuvi's Basemap (to be used if City Navigator is not present, corrupt, unchecked on your nuvi, or when you're outside of the coverage area (e.g., France)

gmapsupp files will only be present if you installed a supplemental map (or installed City Navigator to a SD card, if given that option). If you have gmapsupp files internal on the nuvi and have never installed a supplemental map, let us know since you may need to do something with this now or at some future point to avoid a problem.

Questions

1- If I download the map update to my computer and then use mapsource to put let's say for example Canada on the internal storage will it automatically delete the "old" mapset within the unit ? Do I have to name this mapset or mapsource does it all for me automatically ?

2- If I have the U.S.A. portion already on my sd card will mapsource delete the "old" mapset when installing the new one?

I'm starting to run a little low on internal space and think I might have to be doing this in the near future.

Herb, I think you're saying you have no gmapprom.img on your nuvi and no .img files on the SD card.

If true, then you don't have City Navigator installed to be used.

Try these two things. They can confirm to us that you indeed have no City Navigator installed:

1) Go to your Map Info page (probably Tools/Settings/Map/MapInfo) and tell us what maps your nuvi shows.

2) Try doing a search for an address or creating a route to somewhere using the nuvi's WhereTo.

If your nuvi shows no City Navigator installed or tells you it can't do a search or create a route, then all your nuvi is showing you is the Basemap and it confirms that you have no functional City Navigator. If true, you absolutely must go back to myGarmin and reinstall the current map update.

Mapsource.

@ canuk:
I don't use Mapsource, so I don't know how it deals with partial map installs and deleting previously installed map files. I have done some experimenting with the Map Update installer (the manual method, not lifetime updater). I had the previous CN NA map on SD (as gmapsupp.*), then ran the Map Update installer to install the new CN NA map on internal storage. The installer recognized the old map on SD and deleted it, even though I had intended to keep it. Of course if I had removed the SD card before attempting the update, that would not have happened.

I have also done some experimenting with having two versions of CN NA installed (one on SD and one in internal storage). When the nuvi boots up, it only recognizes the newer map (whether that is internal storage or SD). The older version does not show up at all in Map Info.

Are you referring to your nuvi 255W?

If so, Garmin's faq states that the nuvi 205 series will be given the option to install the map to a SD card:

https://support.garmin.com/support/searchSupport/case.faces?...

If you let the installer do the work for you, the old map will be deleted (internal or SD) and the new map fully installed. So if you're getting low on space, this is the time to invest in a 4 or 8GB SD card and have it on hand for the next map update. And follow alandb's advice and use the manual map updater, not LifeTime Updater.

But to answer your question, I think the following statements are correct:

If you use Mapsource or MapInstall to install a map from your computer to your nuvi's internal storage, I believe it'll be a supplemental map and will NOT remove the older map version (the gmapprom.img file). This will create problems down the line due to having two large maps trying to reside in your nuvi. The naming of the files will be automatic.

If you already have the USA on a SD card and have Mapsource or MapInstall install the new one to the SD card, my guess is that it will replace the older one. It may not--it may depend on whether your 255W can handle more than one supplemental map (e.g., gmapsupp.img or gmapsupp1.img). In any event, I'd make very sure I have a full backup of the nuvi and SD card before trying this.

Although not an issue for the 255W, remember that using Mapsource or MapInstall to install maps from computer to nuvi or SD card, that only the map is installed. Other nuvi series features like Junction View (the .jcv file) will not be installed. So for nuvi series with added features, installing maps with Mapsource/MapInstall is going to give folks a nuvi with an updated map and built-in POIs but will be featureless in terms of JVs, etc.

Thanks

Yes Craig I'm refering to my old 255W that has a lifetime map subscription mrgreen

I was researching/reading different posts concerning this since it's just a question of time before I have to revert to this procedure.

Another member Lilla states in a tutorial that she wrote that to transfer maps it's much better to use mapsource than mapinstall.

I would like to install Canada to the internal memory since I'm in Canada 95% of the time and the USA to the sd card. Garmin doesn't have a download of Canada as it does the lower 49 states thus the reason why I would have to use mapsource to load Canada to the unit and the rest to the sd card.

An easier and probably more intelligent way would be to download the lower 49 states to my unit which will automatically delete the "old" mapset and Canada to the sd card.

I guess the importance is not where the maps are but that they work properly.

Thanks gentlemen for clarifying that smile

Assuming Garmin's faq is right and your 255W will offer you the option of a SD card map update file location, during the next map update (or now, if you want to reinstall the current 2013.20), you can install the full North America to a SD card for use with your 255W in one file and not have to worry about dividing the map or using Mapsource to install map portions.

From all I've read here (and my limited use of my nuvi 750 with all of North America on an SD card), folks are successfully using the map from the SD card and not seeing slow downs, freezes or other issues.

I therefore think it's much easier not to decide whether to put the USA or Canada internal with the other on SD--simply let the map updater put both on the SD and run from there.

Thank you folks.

I followed alandb's advice and downloaded the map update with Map Updater. It is working fine now. I searched for an address and the 765t told me how to get there. It also chowed a map.

The map info is:
CN North America NT 2013.20 D
US & Canada

CN North America NT 2013.20
US & Canada

I really appreciate all your help. This is my first map update since I bought this Nuvi 2 1/2 years ago.
Live and learn. I will move the POI to a SD card to get more space on the unit.
PS. Would it be a good idea to make a hard reset?
Thank you very much.

Before doing a hard reset, be sure to backup your Favorites, since a reset sometimes deletes the current Favorites on the device.

Some folks routinely do a reset after each firmware or map update.

I tend to do a reset only if I see strange results or freezes/reboots on my device.

A reset should not cause you any harm as long as you have a copy of your Favorites to return the the device if needed.

Hard reset.

I have the Favorites backed up but I will wait for now.
I also have the POIs backed up. Then I copied them from the Nuvi to a SD card. Now the Nuvi does not recognize or see the card. How is this done?

GPSmap76Cx handheld, Nuvi 2557LMT, Nuvfi 2598LMTHD

What POI file

did you copy to SD and what folder did you put it in? The loaded POI's are found in internal storage in folder \Garmin\POI. They will have a file name ending in .gpi, such as poi.gpi.

If you copy this to SD card it needs to go in folder \Garmin\POI on the SD card, and you would want to remove it from internal storage to avoid duplicates.

By the way ... glad you got the map update sorted out. If you want an easy way to add about 750 MB of space to internal storage, move the junction view file to the SD card. It is in folder \garmin\jcv and needs to be copied to the same folder on the SD; then just delete it from internal storage after copying it.

Lifetime Updater

I don't think it allows you to download to the SD card.

Garmin's faq

Lifetime Updater:

According to Garmin's faq, SD map installations are offered by both Updaters for several, but not all, nuvi series:

https://support.garmin.com/support/searchSupport/case.faces?...

Your nuvi 650 won't be given the SD option but your nuvi 765T should.

I haven't confirmed this yet, but it's also possible that the SD option may only be offered when the Updater determines that there's insufficient space to install the largest map update that the nuvi is entitled to receive.

Lifetime Updater did.

It gave me three choices.
To the Nuvi only, to the SD card only or to both. I chose to both but somehow that didn't work too good. I had to use Map Updater. Worked a lot better.

HerbSch, did you see an option with Map Updater to install to SD? I don't recall seeing that choice when I updated my 755T. As CraigW said, I think it only gives the option if there is not enough space in internal storage.

I wish Garmin would change that behavior with the installer. It would be better if it always gave the choice to install to SD. Let the user decide!

Maybe I misunderstand your point donz1043, but for City Navigator map updates, this is not correct. A City Navigator map update completely replaces the previously installed map and includes all map data, POI's, speed limit data, lane assists, etc.

It is true that you don't need to manually delete the previous map file. The update installer will do that during installation.

If we're correct, then it should be possible to force a SD installation for the models which can be given the option.

My thought is to install some large garbage files to the nuvi, reducing the free space, then do the map update and be given the SD option. After success, the garbage files could be removed. I wonder how low the free space will need to be to force this action?

Deleting maps in 855

When I select Map Info, I get a list of three maps...2011.10, 2012.40 and 2013.30

I did a hard reset, used MapIntall to load only 2013.30, restarted the NUVI (removed/reinserted battery) and I still show three maps. I am not overly concerned but I'm just thinking of memory usage. I cannot get rid of the 'old' maps.

I read somewhere that new maps 'update' old maps and they are NOT removed by Mapinstall.

What's the story?

You can reinstall a map that Garmin thinks you already have. With your nuvi USBed to the computer, log into myGarmin, then instead of going to myDashboard (which says you already have the latest map update), go to myMaps where you should be given the option to reinstall the current map, 2013.30.

But first, I worry about your current three(!) City Navigators which are there because you've used MapInstall to put some maps on the nuvi. Here's what I suggest you do first: 1) make a full backup of your entire nuvi to a computer hard drive; 2) look at the nuvi (or SD card, if that's where your maps are) and report back to us with the names of the three .img files you have--and if dealing with your 855, however many .jcv files you have. I expect you have a gmapprom.img, gmapsupp.img and another. (Know, too, that your nuvi 855 offers Junction Views--but if you use MapInstall to put City Navigator on your 855, you won't have Junction Views.)

After you tell us what you have, I expect we may conclude that you should keep the gmapprom files, and can delete the gmapsupp files and the others--but don't do this without checking here first. Are we talking about updating your 750, 855, or another? Note that with the 750 and 855, it may be useful to create more room on the nuvi by deleting unneeded voice, help and text files in languages you don't speak.

Once again, my thought after we hear back from you is that once you're down to a single .img file (the gmapprom.img and it's .gma and .unl), you can login and go to myMaps, then reinstall 2013.30.

At the end of the map update, you'll be given the recommended option to install Lifetime Updater. Many here will suggest you not do this--and that you manually update maps in the future. If you currently have Lifetime Updater on your computer, many here will suggest that you uninstall it.

But your tasks right now are to back up your current nuvi, then search and tell us the three .img and the .jcv files' names you see.

Recommended Backup method

This is on topic....
I've been reading about different methods of backing up the Nuvi.

One of the methods (Win7) is to just drag-n-drop the file folders (Garmin and Media) to a different file folder (eg..Drag-n-drop nuvi).

Is this OK?

--
If at first you don't succeed....redefine success

Yes

Yes, on the 855 there are no hidden files on the Nuvi so a simple "drag and drop" of all the files to your computer should be fine as a backup.

DO NOT touch any of the other .IMG files.

In the future, be sure that you are not sending extraneous maps to the GPS unit from MapSource or other map software.

But with a computer backup, you should have the ability to restore any deleted files that need to be kept on the nuvi. I'm glad to see that removing the SD card removed one of the three City Navigators, the oldest 2011.10 map.

Here's my thought:

1) you want to keep the gmapbmap.img (and any other gmapbmap files) which is your nuvi's Basemap, the map the takes over if there's no City Navigator or if City Navigator is unchecked on the nuvi.

2) the gmapsupp.img file (plus, I expect, a gmapsupp.unl and a gmapsupp.gma and maybe a gmapsupp.sum) is older than the gmapprom file meaning gmapsupp.img is your 2012.40 map and gmapprom.img is your 2013.30 (which is about half the size it should be meaning that you probably don't have a lot of the map including Mexico and maybe the southwestern USA since I assume you kept Canada and NE USA.) Oh wait, the 2013.30 map wasn't available on 3/1/2012 so now I wonder. In any event, what I would do is to delete all gmapsupp files (.img, .unl, .gma and .sum) from the nuvi leaving all the gmapbmap and all the gmapprom files where they are. Make sure that the gmapprom files saved not only include the gmapprom.img, but also include the gmapprom.unl and gmapprom.gma--if all three aren't there, STOP before starting this task.

3) If you want all of North America installed when you reinstall the latest map from Garmin, I also suggest that you check your other nuvi files for foreign languages, and delete the foreign language voice and help files that you'll never use. Keep the US and British Help files (en_GB and en_US) and keep eight English voices (American English, British English, the two British pair of voices (Emily and Daniel), the two American voices (Jack and Jill) and the two Aussie voices (Karen and Lee). If you're a Francophone Canadian, keep the French languages voices, too.

4) at this point, I suggest ejecting or safely disconnecting you nuvi, unplugging the USB cable from it, power it up, and confirm that you now see one map in MapInfo, hopefully City Navigator 2013.30.

5) Now you're ready to re-install the latest City Navigator map: reconnect the nuvi to the computer, log into myGarmin, then tab over to myMaps. You should see your nuvi 855 there with a tab offering to reinstall the current map. Click that and start the process of installing 2013.30 to your nuvi. Of course, make sure your computer isn't going to go to sleep over the next two or more hours! When done, eject or safely disconnect you nuvi, remove the cable, fire it up and see if City Navigator 2013.30 is on your MapInfo page and is checked (and is the only map shown as available). If so, you're back to where you want to be but you're still not done.

6) Now that you have a functional nuvi 855 with the latest 2013.30 map and Junction View files, this is the time to make another full backup of the nuvi files to your computer in case issues arise before the next map update comes out.

7) Finally, as you now start using your 855, it should be working but you will notice that Junction Views are pretty plain and can be few and far between. If you reach this point AND if you want to install photo-realistic Junction Views and have many many many more Junction Views, let us know if you want help manually downloading and replacing your current 40-50MB jcv file with a big 750-ishMB jcv file to a SD card for use with the current map.

Good luck.

Success...I think

Down to one map (2013.3). Thank you.
So, I should ONLY use Garmin Lifetime Updater to load maps?
DISREGARD this....our messages crossed each other. I will do as you suggest (not Updater) and let everyone know.

Thanks.

Well done.

Many of us here will suggest NEVER using Garmin's Lifetime Updater and will suggest uninstalling it from your computer. What many of us WILL suggest is to monitor the POI Factory Garmin forum for availability of the next map update, then get the map online from myGarmin/myDashboard which will alert you that a new map is available. If you do follow this thought, remember that the final step of map updates is Garmin's suggestion that you install Lifetime Updater so you'll want to decline each time you do a map update.

A final task:

You say you now have 2013.30 (and only 2013.30!) on your 855. Check your gmapprom.img file. The correct size of this file if all of North America was installed is 1,877,152KB. Also check the jcv file. For 2013.30, the correct default jcv file size provided from Garmin is 44,892KB in size for the nuvi 855. If either file size is different, you really should consider reinstalling 2013.30 from Garmin to get the full map and the proper default jcv file.

Then...if you want the bigger jcv file that works with 2013.30, let us know and we'll start the next tutorial.

Not enough room..

With the 3 maps, I was able to 'load' all of North America on the Nuvi. But now that I think of it, the SD card was inserted...maybe it loaded the maps to the unit AND the card. Anyway, with the card removed I can only load eastern US..ie. NY to Florida and there is no voice activation/navigation available.

It will not let me load to the device AND the computer even though it suggests this would work. The next progress button us greyed-out.

I can remember previouse seeing photo-quality junction pictures and it was very helpful. I would like more of them even though very few are probably available in Canada.

I have an 8GB and a 16GB SD card. Please advise which card would suffice and let's do it!!!

Hmm,

The nuvi 8x5 series is not one of the series in which Garmin offers direct installation to an SD card of map updates so any map files on your SD card occurred due to actions on your part.

However, if you delete the unneeded voice files on your 855, you can install all of North America, keep your voice activation files, and still have oodles of free space for future larger map updates.

I think you should first get the current 2013.30 map on your nuvi as you wish it to be, then we can work on the large photo-realistic jcv file, since that will require working with an SD card once again. I think that that our Canadians using the large jcv file report many JVs in Canada but I could be wrong.

To install the large jcv file, you need to create a /Garmin/jcv/ folder on your SD card, then install the large jcv file there. The file can be found in rame1012's post on page three of:

http://www.poi-factory.com/node/38056?page=2

and other places. Note that the file offered by rame1012 through Dropbox frequently throttles back downloads so if you can't get the file the first time, go back later or get the file from another source--I see that the file is available for downloads right now. (Garmin used to provide a link to the large jcv file but stopped offering it with the current map.) Also needed is to disable the small default jcv file in the nuvi--an easy way to do this without losing the file is to rename it with a final .disabled, as in
DxxxxxxxxxxA.jcv.disabled.

Know also that jcv files are linked to specific map update versions. So when the 2013.40 map update comes out, you'll again get the small default jcv file, then have to find, download and install the large jcv file intended for the new map. The best way to learn about availability of the map update and the large JCV file is to monitor the Garmin discussion here at The Factory. By the way, someone here has confirmed with Garmin that they're OK with folks sharing the jcv file from map updates.

Some extra details can be found in this somewhat dated thread:

un-nessary file?

I have not tried the large junction-view file yet, but I have a question first...

Yesterday when I 'updated' my 2013.3 file there was a power-bump during a freezing rain occasion.

I was concerned about not enough space to load NA. and I looked at the files in my NUVI. There is a disc image file called 'gmapprom' with no extension and a size of 975,712KB. Could this be an 'interrupted' corrupt file? Should I delete it? There is a gmapprom.img file of 1,671,200KB right below it.

I'm not sure why I do not have enough space left for all of NA but only the eastern USA.

I checked a virtual junction view (there are none in Ottawa without major traffic problems) and it shows that I have junction view capability.

I have eliminated all voice files except US.

thoughts?

another Q?

You mention not using Lifetime updater...what method do you suggest?

Garmin's

Garmin's Map Updater program, which is what will be used if you download a map update from your myGarmin.com account.

See CraigW's post above:

"then get the map online from myGarmin/myDashboard which will alert you that a new map is available. If you do follow this thought, remember that the final step of map updates is Garmin's suggestion that you install Lifetime Updater so you'll want to decline each time you do a map update.

Note, there is a big difference between Garmin's Mapupdater Program and Garmin's Lifetime Updater Program. wink

Your guess...sounds pretty good to me. There definitely should not be a 975MB file with no extension on your nuvi. What I'd do is temporarily move the file to a computer, then see how the 855 behaves over the next few days.

I still wonder why after deleting non-English voices, help files, etc., that you don't have room for all of North America, especially since your img file of 1.67GB is so close to the full North America file of 1.88GB. Yes, the 975MB file would be a problem with putting all of NA on your 855, but Garmin's alert that you didn't have enough room for all of NA occurred before power-bump and phantom file appearance. I have a few extras on my 855, the full NA map (1.88GB img file), my voice recognition still works, and I still have 670MB of free space.

Just checking--are you using a PC or Mac? If you're using a Mac, are you emptying your Mac's Trash which apparently is needed to truly delete files from your nuvi. If you look at your nuvi drive with your computer now, how much free space does it say you have?

It is good to hear that you have a 2013.30 map installed and have JVs showing. If you have no plan to visit the western USA before March, you could just live with what you have now. The 2013.40 map will likely be out sometime in February. It would be nice, though, before updating to 2013.40 that you find out what's keeping you from loading all of North America.

If things are working now, then downloading the large jcv file should be worth doing. If you download it from rame1012's Dropbox, it'll be a zip file that you'll need to unzip, then copy to the SD card. More JVs and photorealistc JVs are worth the extra effort. Note that when 2013.40 comes out, you'll still be back to a small default JCV file until someone offers us a link to get the large file.

Instructions followed, now to test (Nuvi 855)

I deleted the file I expect was an incomplete image file, the Audible snippets, all except English voices and all but english help files.

I downloaded the large .jcv file and renamed the one on the Nuvi. I probably could have loaded the large .jcv file directly on the nuvi because I've got over 1GB space with Eastern US maps loaded.

I think I will leave it like it is for now and search for a local JV. I'm driving to Orlando and those maps are loaded. If I go astray and cross the Mississippi, I'll reload more maps.

I will post observations within several days. Still some shopping to do so I expect I'll find some JVs somewhere.

Thanks for the help.

Yeah. One will update the map. The other will have you turning to dust before it updates a map.
