Using Multiple Maps on the Garmin 60CSX
Say you have a map of Australia and a map of New Zealand. Can you upload the files separately to the 60CSX and give them different names, as on some Garmin units, such as gmapsupp.img, gmapsup2.img, etc? The answer is no. Am I sure? Yes. So does that mean no? Yes, it's a "no". Forget it. Sorry everyone, the 60CSX can only use one "img" file at a time. Thank you Garmin. You'd imagine that this would be a simple thing to fix in firmware upgrades. My feeling: it is, they just don't want to do it.
Thanks. I found that link and it is an interesting page on the 60CSx. Lots of info there although some of it is a bit misleading. I suspect this 'only one img file' feature is not limited to the 60x models, but also applies to the 76x models and probably a few others as well. Good to know. Given that memory cards are so cheap these days, it might be just as fast to load one img file to a card and switch cards. Certainly faster than hooking up a laptop and all the related cables.

Upload the new img file to your unit. Rename it gmapsupp.img. It should work!
I'm sure it would. I have only used gmaptool a couple of times and there is a newer version now available than I have. Time to get updated!

I think I will take the trails gmapsupp.img file and try and convert it for use in MapSource. That will make it the most flexible and usable with all my other off-road and back country maps.

Thanks again for the pointers!
