How many maps can I put on SD card?

 

So I am looking to take a map of Eastern Europe and India with me, and want to put them on an SD card. What do the maps need to be named, and can they be put on a single SD Card? Thanks.

EDIT: I have a Nuvi 200

It depends on the model. If

It depends on the model. If you have an older unit, you're limited to just one map: gmapsupp.img. Newer units have no limit because they can carry any name you wish to give them, so long as they have the .IMG extension.

You need to tell us what model you have so we can tell you with absolute certainty.

But on an older unit couldn't you have a map called India.img and one called Europe.img on the SD card. The only stipulation you'd need to follow is that you rename the map you want to use gmapsupp.img when you need to use it.

Maps

I believe with the older units (like my 775T), only one gmapsupp.img was available to be added. On others, adding the "Maps" folder on the card was good for a few; i.e. Canada, the US East, US West etc.

Yes,

Yes, only one gmapsupp.img file at a time but you can have any number of .img files on the card. You just have to rename the one you want to use, to gmapsupp.img before it's recognized by the older Nuvi. Of course you'd have to rename the current gmapsupp.img before you did that.

Hmm

Rick, I'd have to disagree on adding more than one on a card on an older unit. It can't be done on my 775T. I've tried many times.

While a bit of a hassle, if

While a bit of a hassle, if the OP didn't wish to go through the process of renaming his maps each time he wanted to change countries, he could combine the Europe and India maps into one gmapsupp.img. I do believe that MapInstall will allow him to do so, but if not there is software out on the Internet that will allow him to do the map combining if MapInstall won't.

Of course, the thought exercise is moot if the OP has a newer GPS.

Sorry, I have a Nuvi

Sorry, I have a Nuvi 200...."newer" but basic....

Thanks for the help!

That's not newer given it

That's not newer given it was discontinued two years ago if not more. Newer would be the 1xxx units.

Whether you can have multiple maps on the SD card or not is still being debated, but the only map that will be recognized on SD card in your device is gmapsupp.img. So if you want Europe and India, you'll either be renaming maps to switch or combining the two maps into one file. Hope you have a large SD.

Why not

Just buy an extra 2 gig SD card and carry it with you ??

A great plan

Since it's doubtful that anyone needs a route from Eastern Europe to India or vice versa, putting Europe on one SD card and India on another--then powering down and swapping cards--seems by far to me to be the easiest solution.

Use Micro SD cards

Just use separate cards to hold both maps as was suggested. I use Micro SD cards with the SD adapter. They are tiny.

Assuming these are Garmin

Assuming these are Garmin maps that can be installed using MapInstall, he should be able to combine both maps into one gmapsupp.img by selecting the regions for Europe, then switching to the regions for India. When MapInstall runs, it will combine both into a single .IMG file.

Couldn't get it done on my 3790 either.
I have Topo Maps and dictionary files on the sd card.
Tried to load another set of Topo Maps since they are quite big but couldn't figure out the file structure.
Tried it a bunch of different ways no go.

Try /Garmin/Maps on the MicroSD. Put your maps there and see if you get any results.

Thanks for the all the info

Thanks for the all the info cause I was planning on copying more maps to my Nuvi.

Try the following names

I believe that the following names are recognized on some of the older units.

gmapsupp.img
gmapsup2.img
gmapprom.img
gmapbmap.img - (this is the basemap so you might want to leave this one alone... not sure if the unit will load this instead of the normal basemap file on the GPS but it might cause problems with routing if it does. Someone else here with more knowledge can probably give more detail on this)

While you're loading different maps, check out openstreetmap.org - those maps generally include detail that's not in the commercial Garmin maps (and vice versa). The Garmin maps tend to include more commercial detail where business have paid for inclusion but OpenStreetMap generally includes more detail on smaller businesses and other places of interest, especially if you're off the beaten path.

Should be easy on the 3790 unless something has changed in a recent update.

All you need is a folder called MAP (not MAPS) and it's in the root of the SD Card, not in a Garmin folder. At that point you can install as many maps as you want in that folder. The map file names can be any name you want (not just gmapsupp, etc.) like California Topo, or Pacific Northwest Topo, as long as the file extension is always .img

Don't think it's the same on the 765.

I don't know if the 765 was an update to the 760 like the 2x5 series were updates to the 2xx units. Regardless, the location of the maps will be in one of the two places:

SDCard/Garmin
SDCard/Map

I went and double-checked to make sure. My previous post was completely wrong and means I should not rely on my memory. grin

I just looked at my sd structure again,
The root has gmapsupp.img and gmapsupp.unl
in it. They aren't in a directory. Bin quite a while since i tried adding any maps to this unit. I do remember that it wouldn't read the directory. Question is, did i use Maps instead of Map as you pointed out. I'll try that. Thanks

I've read somewhere that this is the correct method for <1000 units.

@ Speed2

It had been awhile for me as well when I posted earlier today so I went through the exercise of putting a map on a new SD card for my 3790. It definitely goes into the MAP folder in the root of the SD card.

I actually created the folder Maps and found out quickly that that didn't work smile

1 or 2

@ t923347

1 map or 2? I have one already there but its in the root, and a directory called Lexicon for my language files. I do not have a directory called Map for my topo image, and it reads it. I think I get what your saying. Make a directory called "Map", dump the topo file in there from the root and put another one in there called something else. Actually could make a copy of what i have and rename it and try that way?

The 765 I believe is limited

The 765 I believe is limited to one working map on the SD card at a time: gmapsupp.img. While you can have as many maps on the SD Card as will fit, only the one named gmapsupp.img will work. This is different from the 1xxx and later units which do not have this limitation.

The internal memory can handle multiple maps, but they need to follow the general naming structure that Dorkus Nimrod provided some time ago.

P.S. My 200W has the map located in SDCard/Garmin and not the root.

Just to

Just to be sure, we are talking about the 3790, right?

If so you need a folder on the SD card called MAP

In the MAP folder put as many map files in there as you want. They can have any name, for example:

TopoMaps North West.img
TopoMaps South West.img
OpenStreetMaps Mexico.img

Boot the 3790 with the SD card installed and you should see all of the .img files you put in the MAP folder under Tools - System - MyMaps.

yep

@t923347

Now just a reminder, i have no folder for my map on there atm and it reads my topo image just fine. Since there's an unlock file there also, i would say that Topo mapsource put those files in the root onto my sd card.

Sorry to resurrect this

Sorry to resurrect this thread but one more question:

I want to have 3 maps total. Two on the Unit itself (gmapprom and gmapsupp) and wanted to have a 3rd gmapsupp on the SD card. I can't get the Nuvi 200 to recognize the 3rd map -- it does see the first two that are on the unit.

I tried naming the 2nd map on the unit gmapsup2 (skipping gmapsupp on the unit) but it wouldn't read EITHER gmapsupp from the SD card or gmapsup2 from the unit.

I know I could carry the extra SD cards -- trying to avoid that. Please let me know if its possible to do what I want. THanks.

Try renaming gmapsupp.img on

Try renaming gmapsupp.img on the internal space as gmapprom1.img and see if that allows the map on the SD card to be read.
