Garmin Map Updates File size

 

I recenlty bought a nuvi 50LM that I like very much, but I see there is only 1.76 GB of total space.

After installing the custom POIs there was only 137 MB of space left. I deleted a bunch of voices, help files and auto icons and it bumped up to 185 MB. I can delete a bit more buy I doubt it'll go much over 200 MB.

Garmin couldn't tell me the update file size for the lower 49 states maps which it seems I have on my unit. Does anyone know what the approximate size of the 49 states map update might be?

It seems unlikely I'll get more than 2, if any updates without having to install a micro SD card. Once installed do you have to keep touching the screen to get things to load, or is it a one time thing. I searched the forums but didn't really see this.

I apologize for my GPS ignorance.

Size

City Navigator® North America NT - Lower 49 States
is 1.33 GB in size

(under requirements)

You just have to put a check once in the map info screen after the initial download.

If I am doing this right 1.76 GB is 1760 MB and after you loaded "custom" POIs you had only 137 MB meaning your "Custom" POIs took up over 1.5 GB.

What did you load?

1 GB = 1024 MB

1.76 GB = 1802.24 MB

You sure about that?1.76

You sure about that?1.76 equals total space=1.76. According to canuk City Navigator® North America NT - Lower 49 States is 1.33 GB in size https://buy.garmin.com/shop/shop.do?

After I posted my question, I realized that ericuby had said "total space" and I had read it as "free space" Before I could "edit" my comment, alandb got me on the fact that a byte is 1024.

What I should have asked is what the "free space" was before the "Custom" POIs were loaded.

Or maybe, I would have just deleted the whole post because I really was not responding to ericuby's implied question as to how long he would be able to update his unit (at least, that is what I now think it was).

Ego Te Absolvo

No problem at all jgermann.

I think all my custom POIs take up only 100 - 200 MB, so Garmin itself took up most of the 1.76 GB total space and it seems 1.33 GB was the 49 states map.

I don't know if whatever update comes out for my 49 states map in a few months (per Garmin) will be a few hundred megabytes, or over a gigabyte. Either way, I will have to buy a micro SD card as the unit has very little free space left.

Everytime I get a 'junction view' on the GPS screen I smile. I'm easily amused. grin

Total Space is 1.76 GB

The total space is 1.76 GB and I guess the map takes up 1.33 GB of space.

Of the remaining 0.42 GB (420 MB) Garmin used 283 MB for their 'stuff' leaving only 137 MB offree space before I deleted voices etc to get up to 185 MB.

Only 11 more MB

It looks like if I delete the taxt and keyboard files, that will only free up about 11 more megabytes of space.

And to complicate matters, those files done list the names of the languages, though I'm pretty sure everything from the letter 'H' on down is not English. I doubt I'll delete them just to gain 11 MB.

Will buy a micro SD card this weekend.

Wondering...

If calculations are correct, in another two weeks NA 2013.20 will be out. I am wondering how much bigger that one will be.

get card

CN NA 2013.1 is 1.62GB (whole North America). CN Europe 2013.1 is 2.5GB (whole Europe). And for sure they will be bigger with next update. How much, it depend on new data in maps.

Practically you may be sure, that internal memory will last for not more than 3 updates. When I bought my 770 with NA i EU maps it had some space free. After one update (if I recall correctly) there was only space to update one of my maps. So I get rid of all not needed voices and all other unnecessary stuff.

It was good for one or two updates. After that I moved one of maps to SD card and so far I should have place for few more updates.

Just get use to fact, that Garmin isn't really generous with "user" space on device. I guess they are not really into "life time" use of device. So either you start playing with splitting maps between GPS and card or when you run out of space buy new GPS.

Or you learn to transfer the

Or you learn to transfer the entire map to the SD/MicroSD card and leave the internal space free for something else. For example, CNNANT 2008 Lower 48 States is on the internal space of my 200W. The current map is on the SD card.

When my 1300 runs out of internal space, the 16GB MicroSD I have in the slot will end up receiving all my maps. The internal space will get the JCV file and a copy of my home state, simply to bypass the "No files that support routing" error that would pop up.

about a check mark

I have a New Map version on my SD card and an older map on my garmin what happened if I put the check when I select MAP INFO on both of the map should it cause any problem, or just check the newer map version.I also like to add that the map that I have on the garmin is named GMAPPROM.IMG and the one on the SD card GMAPPROM.SUPP.

And If I first back up on my pc the original map that I have on my garmin and replaced with the one on the SD card and renamed GMAPPROM.IMG would my garmin still work?

don't do it

If you have maps that cover this same area (or are overlapping on part of are) and you select them as active together there may be different effects. It may work fine, but sooner or later GPS may behave in weird way. What may happen is that when you want to navigate to point you may get info that it can't trace route. Or route may be weird. And there can be problem with finding addresses.

As rule if you have two or more maps covering this same region you are using at the time only one of them and turn of others. Otherwise your navigation at some point can get insane without obvious reason. You can try, but once it starts behaving strange just remember to turn off unnecessary map.

I do believe you incorrectly identified the map on your SD card as "GMAPPROM.SUPP", it should be "gmapsupp.img".

As grzesja indicated, it's not wise to have two maps of the same area active at the same time. One of the problems that may arise by doing so is the SEARCH function not working properly.

You should be able to use the map on your SD card by backing up your old map to your computer, then remove it from the Nuvi, then copy the map from your SD card to your Street Pilot and renaming it to "gmapprom.img".

Before you do that, make sure you will have enough room on the unit to accomodate the new map. Having the SD card inserted, open up Windows Explorer, right click on the Garmin drive and select properties, you will see how much free space you have left.
Now look at the gmapprom.img file and look at it's size. Next look at the file size in the SD card of the map, Calculate if by removing the existing old map and adding the new map (size is larger) that there will be sufficient space to accept the new map.

Note: Having no experience with Street Pilots I don't believe they had unlock codes on these older units. With newer units you must have an unlock code that accompanies the map you have installed.
If the map you have on the SD card has an unlock code to it it won't work on the Street Pilot since the code is for the SD Card only.
