Thread: Garmin Trail maps, most of the USA

No joy. I renamed it to gmapsup2.img and transferred it. Now the Garmin folder has two .img files - gmapsupp.img and gmapsup2.img. I think that's what you meant me to do. Alas, it does not show up on my 60CSx in the list of maps to Show/Hide.

If I name it gmapsupp.img (replacing the original file) then it shows as 'trail 100' and is visible, but I don't see how to make it show with City Nav.

OTOH, I left it named gmapsupp.img and put it in the Garmin folder of my StreetPilot 2730 and Voila!, there it is! On this gps, the built-in map is City Nav NA v2010.20 and is named gmapprom.img, so there is no conflict in names.

Unfortunately, the 2730 is hardly the gps of choice for off-roading 4WD trails!

More experimenting is needed for the gps units that do not have a built-in map, like my 60CSx. I will check to make sure my firmware is the most current.

Thanks!
