It sounds like you are trying to double-click, or otherwise open, an.img file intended for a Garmin GPS. You shouldn't do this. Double-clicking tells your computer to 'find the program that will understand.img files, and open this with it'. But this.img file is not meant for a program on your computer. It's meant for your Garmin GPS unit. Assuming you have an SD card installed in the card socket for your Garmin, simply do this: • Connect your Garmin to your computer via a USB cable. • Put your Garmin in USB Mass Storage mode.
(On an eTrex, this is typically done by going to the menu screen, then Setup ->Interface ->USB Mass Storage.) • The Garmin should show up as a removable disc (like a USB stick) in the usual place.

On a Mac, for example, this will be on the desktop. • If there isn't a folder on the Garmin called 'Garmin', create one. • Into this folder, copy the.img file that you downloaded.
• Rename it to gmapsupp.img if it's not already called that. • Eject the Garmin as you would a USB stick. Again, on a Mac, you do this by dragging it to the trash.
When your Garmin reboots, you should now have the OSM map displayed. I was unsure how many maps I may want on the 30x so after talking with the Garmin helpline (who were helpful), they said it would support 32GB. Given most of the maps I see are about 2GB, I then at least have the option of having coverage on travels.
A tutorial detailing how to use Garmin MapSource to load maps to your map capable GPS unit such as the Gpsmap 60x(s)x, Etrex, Legend, Dakota, Oregon, Colorado. Jun 18, 2016. This is the simplest tutorial on how to add or update maps to your Garmin Sat Nav. Garmin maps are simple.img files (files with.img extension). So updating or adding maps is as simple as copying and pasting a file, which has to be named gmapprom.img or gmapsupp.img. In some places, you may find.
E.g., I need decent maps for hiking in Germany and Brazil/Argentina on an upcoming trip. I would not expect track logs to take much room, but good to have the larger card so I don't have to worry. I presume I should be able to save the logs to the micro-SD card? Thanks nevw for the gpx tracks info.
Bummer, but as you say, they are smallish files so can stay in main memory. So what happens if you say 'Archive'.
One would hope that they should be able to be stored and read from the SD card. Think of a standard computer that can only read some info on an SD card. People would get pretty mad. I just got my 32gb micro SD card and did a straight copy of my Garmin Oz/Nz topo 4gb micro SD content to the 32GB card (same folders) and it says it can't unlock the map. Now I have to wonder why I bothered with the larger card if you can't copy purchased maps to it!
That is pretty nasty of Garmin, surely! This needs more homework, and maybe a call to Garmin. One wonder why they even bothered to tell me that the 32GB card would be supported. The garmin maps are protected from copying as expected, though JAVAWA may help to back up to your new card(?) You should become familiar with - in particular the JaVaWa Device Manager for your gps and JaVaWa GMTK for the maps on your computer as these will sort out many issues you come across from time to time. You can copy all the archive files to the card and use from there if you wish. On mine I must do this manually.
Your new card hopefully gets some use with the travels you have planned with downloaded OSM maps and you can also use to backup photos. You may end up wanting to put paper maps as customs maps on your gps too For Garmin issues that are not osm related, I recommend asking the experts in this newsgroup. If I do a straight copy of my two Garmin maps on the new 32GB microSD card, the GPS doesn't recognise them even though BaseCamp does. That I find odd. So I rang Garmin to get the official line on maps and SD cards. They said 'Strictly one map/sd card'.
