Great news

That's great. t92, I like your new image, too--there's no harm in admitting to being a geek twisted

Questions often arise regarding the large jcv file each time a new map update comes out, especially from new users here at The Factory, such as: what is this file, do I need it for my GPS device, etc.

To me, there are basically two groups of people that will want to use the large JCV file, which requires manually downloading the file, copying it to the nuvi and disabling the default jcv file:

Group 1: These are folks with older nuvis that can display full-screen Junction Views but receive a very small file from Garmin during map updates. These folks have models including the nuvi 8x5, 1xxx and possibly other models. (The nuvi 7x5 model doesn't need to manually add the large jcv file because Garmin supplies it during the map update.)

Group 2: These are folks with newer nuvis who receive the split-screen Junction View images but wish to have the full-screen views fill their screen for a few seconds rather than have a longer view with a split screen divided between map & view. The consensus I read here at The Factory is that the vast majority of split-screen nuvi owners prefer the default split screen and therefore can ignore any large jcv file discussions.

If you don't fit into group 1 or 2, you can ignore all discussion of Large JCV files now and into the future. And as long as folks keep backups of their original jcv files and are familiar with file renames, copy&paste, etc., there's no harm in trying the large JCV file, since it can always be removed and replaced with the original Garmin-provided file.

Where to put large JVC

can you run the large JVC file from your sd card, and if so, what should the file tree look like?

Yes you can. Copy the file to the card's /garmin/JCV/ folder that you created.

Be sure to delete or rename the jcv file in the nuvi after keeping a copy on your computer if it's needed again. If this is for your nuvi 855, after adding the new large jcv to the SD card and disabling or removing the small jcv file in the nuvi, remove the nuvi battery and then reinstall it--this will reboot the nuvi so it will find the correct large file and use it.

slow download

Thanks, and that link did work for me, but starting about 10 or 12 hours before I am making this post the download speed was exceptionally slow, typically 30 to 50 kB per second, so it took over five hours to complete. Maybe too many of us jumped on it together for the server capacity that they supplied.

Run large from sd card

CraigW,
Thanks, that worked. I had the tree structure right but didn't do the reset.
Thanks again.

Good to hear. Yes, the nuvi 8x5 series has always had some quirks required that aren't needed for other nuvis.

Your 855 won't have all of North America installed with this new map update. If your SD card is 8GB, you can go back and reinstall the map update using alandb's cloning technique and will have the entire North America map installed:

t923347, thank you for the link to the JCV Full Screen file.

Unlike the majority here, I am a charter member of both groups CraigW cites. My nuvi 3760 gets only a very, very limited version of the split-screen JCV file the nuvi 3790 and others get. Plus, I like a quick reminder about the exit and for the JCV then to get out of the way. I rely more on lane assist.

I'm delighted that Garmin continues to provide the large JCV Full Screen file.

It's a checksum file and can be deleted without a problem. It's tiny so there's not really any benefit to deleting it though.

Problem with .jcv file

Downloaded and installed the large JCV file last night.

Discovered a problem on the way to work. When approaching the I-64/I-664 (MM 264) junction from the west, my 3597 displayed the Junction View in full screen mode for about 15 seconds, then it reverted back to no Junction View. Did the same thing for my exit at 35th street.

Coming home, it displayed the 35th St. on-ramp as usual. But when I got back up to the I-664/I-64 junction, it went full screen again for about 10 seconds or so and then back to no JV. All JVs turned on at the usual spot.

Re-downloading the D3060130A.jcv file again and will re-install it.

According to GPSMAP.us - it's supposed to be full screen. Is this true? Or are there more junction views? Or both?

** Edit **
Don't think I would dl anything from that site. All "FREE" and no ads. Looks like a good site for your PC to catch something at.

Yes, the full screen large jcv file (700+ MB) displays for a few seconds, then disappears.

There are some folks with default split-screen JV that prefer this full-screen version, but most split screen folks who own a 3597 like yours stick with the default split screen display.

The large JCV has no more junction views than your default JCV file. The reason your default JCV file is smaller is not due to fewer JVs but rather to the smaller number of pixels that need to be displayed.

Yes

Yes, the downloaded file is FULL SCREEN views. It is provided for those GPS models that don't get a full JCV file because the map update process determines that there isn't enough space on the Nuvi to hold the large file. THESE ARE OLDER MODELS LIKE THE 1XXX AND SOME (MOST) OF THE 7XX AND 8XX DEVICES.

If you have a newer Nuvi that displays junction views as a split screen (displays the view on one side of the map screen and the map on the other) there is NO need to download this additional file UNLESS you want to replace the split screen view with a full screen view.

The large downloadable file has exactly the same views in it that the split screen devices get automatically as part of the map update. The file size of the large downloadable file is approximately double that of the split screen JCV file and that's because the views on the full screen are twice the size of the pictures on the split screen.

I believe, as I mentioned above, the major reason it is smaller is because the individual view (pictures) are only half the size of pictures in full screen file. Which a guess could be referred to as displaying less pixels. wink

Yes, I discovered that this AM and don't like that disappearing JV.

Getting ready to restore original JCV file as I type.

Thanks for the info.

I realize now that the file is twice the size due to the images doubling in pixels to fill the screen, and not because there are more JVs in the file.

FYI

I really appreciate the efforts people have made for the community.

FYI...

I have used the large JCV in the Garmin directory (without the additional JCV subdirectory) on my microSD card in my Nuvi 1450 for multiple versions, with no problems now.

Just in case one should want a little less complexity. It doesn't make much sense to have a a directory for a single file that is unlikely to be joined by other files in the future.

pratzert, which nuvi did you add the large JCV to? Your profile only lists two Streetpilots that can't display JVs.

How do I install large JCV file on my Nuci 1490lMT ?

I heard you get wiser as you get older...well doesn't seem to hold true for me.

I must be having a senior moment. I can't figure out what exactly I need to do to install large updated JCV file to my Nuvi.

I have latest mapset loade...2014.4, but my JCV file is small at around 25MB.

I forgot to say I have a microSD installed in my unit.

Any help in the form of step by step would be greatly appreciated.

Thanks in advance.

Remember that the large JCV is version-specific so the process will need to be done with each map update.

Tell us where your 2014.40 map is installed--is it (or whatever of it that fits) installed to the nuvi or is the map installed to the SD card? How much free space is on the SD card (or alternately, tell us the size of the SD card). You need space on the SD card to hold the large file. I recommend a 4 or 8GB SD card, large enough to hold the full North America map update plus the large JCV file.

1) download the large JCV to your computer.

2) find the small jcv that came with the map update and rename it by adding a .disabled at the end; i.e., DxxxxxxxxxA.JCV.disabled.

3) if the SD card doesn't already have it, create a garmin folder and a JCV subfolder.

4) Copy the large jcv file from your computer to the SD card's \garmin\JCV folder.

5) test it out. If all works, you can delete the small disabled file from the nuvi--or better yet, move it to storage on your PC. Disabled JCV files will not be removed during future map updates so you need to keep tabs on them so that several don't build up wasting storage space.

As always, it's best to do a full backup of the nuvi to storage on a computer or other drive before starting to tinker with files manually.

Mapset update & large JCV file

CraigW, thanks for your detailed reply...lots of good guidance.

Here's the status of my Nuvi 1490LMT as of now: I've run Garmin Express...looks like it was a success in installing 2014.40 (not quite sure where to look for map files) but my Nuvi claims they are installed. Any chance you can point me to file I should be look for ?

I have my PC set to display hidden files. If I look at JCV file found under .System it reflects small JCV file (25,302 KB) D3153130A.JCV

I have an 8 gig microSD installed. It currently has 2 folders..."Garmin" and "Map". There are 3 files in Map folder...gmapupdate.gma (3KB), gmapupdate.imp (1,972,288 KB) and gmapupdate.unl (1KB).

Do the above files seem to be in right location and of the right size ?

I've downloaded large JCV file noted in this posting but I am hesitant to move forward until I have better feeling about the 2014.40 update as it exists on my Nuvi as of right now.

Any additional help you pcan provide will be much appreciated.

I keep asking myself "why does Garmin make these updates so difficult"? Seems updates should be a piece of cake if they offer lifetime updates as part of purchased package.

Hmmm

Hmm, some odd things here.

Can you check your nuvi to see what map you have? Tap Tools/Settings/Map/MapInfo (or maybe Tools/Settings/myMaps) and tell us what CN map is displayed: 2014.40 All, 2014.40 Lower 49, etc. I ask this because your map seems a smidge smaller than what I expect the full North America map filesize should be (about 2.2GB) and if your map update was installed to the SD card, I expected to see the biggest 2.2GB .img file. Maybe it's the filename used by your series of nuvi, but I've never heard of a file named gmapupdate.img (I assume you had a typo and meant to write .img rather than .imp). I was expecting your map file to be named something along the lines of gmapsupp.img or gmapsup1.img. In any event, to me it appears that your map is installed to the SD card in the Map folder and is the trio of gmapupdate files.

Given the above confusion, I still think you can proceed to install the large JCV file, since all we plan to do can be undone if needed and because we will not touch any of the map files (your gmapupdate files).

1) Rename the small (25,302KB) JCV you found by adding a .disabled to it.
2) If there's room on the device, you can copy the large JCV file to the same folder (.System) where the small JCV was found.
3) If there's not room on the device, or if you want the JCV file to be on the SD card, I suggest making a JCV folder inside the SD card's garmin folder and place the large JCV there.

I think I've read that some folks have found that the jcv file can be in any of several locations and will work. But with a current North America map update, there must be only one associated JCV file so it's essential that the small JCV be disabled for the large JCV to work.

A quick route (real-time or simulation) along an interstate highway with an interchange or exit will quickly show you what you have: if you see no Junctions Views, you have no active JCV file; if JVs are still pretty minimal, you are using the small default JCV file that Garmin provided with the map update; and if you have more and much more detailed JVs, you're now using the large JCV file.

Lastly, regarding you "why does Garmin" comment, the small JCV file is offered as the standard JCV file with map updates on these older nuvi models because they're space-limited--and offering a smaller JCV file will allow a larger map update to be installed to the nuvi. The large JCV was made available to users only after many user complaints to Garmin, and to Garmin's credit, they are offering the large JCV file to users willing to manually improve their JV displays. Garmin did not need to do this so I commend them. On the other hand, since Garmin has also started to allow map updates be installed to SD cards, it does seem that they could once again use the large JCV file in their default map updates. Just my thoughts. It is also possible that Garmin would prefer having users update to newer nuvi models to gain these new features--and for the average user unwilling or unable install the large JCV file, they may buy a newer model rather than go to the effort of squeezing a bit more function out of their older nuvi. I'm OK with that if that is part of Garmin's reasoning.

Good luck and shout back if needed.

I really do hope that you have a full backup of the entire nuvi and SD card on a computer in case you do something that requires going to the backup to restore a file to the nuvi or SD card. You definitely know what you're doing file- and folder-wise so I'm not too worried, but it's always better to be safe rather than being sorry.

Map Status

CraigW,

I checked my Nuvi...current mapset "CN North America NT 2014.40". I also rechecked filenames found in "Map" folder on my SD card: gmapupdate.gma, gmapupdate.img (1,972,288 KB), and gmapupdate.unl

My PC recognizes Nuvi as drive "E"...microSD card is "F".

I ran a quick route simulation...junction views displayed were full screen but low resolution.

I'm going to download large JCV file and copy to subfolder "JCV" created under "Garmin" folder on SD card. I will also rename samll JCV file D3153130A.JCV.disabled...this file is located in Nuvi ".System" folder.

Correct. I was predicting what the link will become when the map 2015.10 update and its large JCV become available. Since the 2015.10 map is probably a good month away, the link for that map's large JCV file goes to a non-existent web address for now. The test will be if the link works when/if the 2015.10 large JCV file does become available.

thanks.

appreciate the heads up.

Update Success !!

Looks like download and install of large JCV file to my Nuvi was a success.

I ran a simulated route...displayed quite a few junction views on the Interstate.

Only comment I regarding this large JCV file is I thought previous large file depicted junction views "more photo-realistic". Anybody else believe this to be the case ?

Success--or not?

Good luck if you did succeed. But the image quality should be shockingly improved with the large JCV file and more photo-realistic. I worry that you still have a copy of the default small JCV active. If future tests continue to not look better than before, do a search of your nuvi and its SD card for all JCV files. The only one you should see is the large one you manually copied. I wonder if you have a smaller JCV either in the nuvi or on the SD card that you've not yet disabled or deleted.

Success - I Guess

I've gone back and checked both my Nuvi and installed SD card and found NO evidence of small JCV file that has not been disabled or deleted. I ran another route simulation heay with Intersate junctions/exits...junction views displayed still look to be of lower resolution than what I remember seeing before this update. Last mapset I had was 2013 with large JCV file. Might be my eyes playing tricks but I just recall seeing junction views that looked as sharp as a postcard.

If it wasn't such a pain in the "A--" I would re-intall my old mapset and large JCV file from my backup just to see if I'm dreaming about something that may never had been.

It's very strange.

I just picked up a 65LMT and I can't see the files I would normally view in Windows Explorer. The device indicates it handles Junction View, but I can't find a JCV file. In fact, I don't see the .System file or the other files I'd normally see. There is a Garmin folder, bit it only contains diagnostic stuff. I don't even see the map image sad
