Colorado firmware 2.95 Beta in GPS technology and devices Posted July 24, 2009 I've got a couple of questions about img map files. I understand how it would be useful to have multiple img files on my Colorado (which had all kinds of problems running the 2.94 beta but appears fine with 2.95), but I don't know how to produce them. Mapsource produces (if I recall correctly) map files with a gdb extension. How do we obtain img files, or convert gdb to img? And once we have the img files, should they be loaded into the "garmin" folder on the Colorado? Jon, If you save a Mapsource "instance" then you'll get gdb file by default. However if you use the map select tool and place map segment(s) into the Map tab on the left, then use Send to GPS, that file will be called gmapsupp.img, that's the img file you rename. Thank you! So if I want multiple img files, I would have to send them to the Colorado that way, then remove them, rename them on my computer and reload them in the Garmin folder? I guess it's not all that clunky for the convenience of having multiple img files, but there's no easier way?
