Hi. Was chatting with Garmin and they say they can only “guarantee” their proprietary maps. Ok fine. But, their owner’s manual for this product doesn’t say whether I can get open source files into it.
Will this unit work with open source files like OSM?
My purpose is to take a year long road trip from the US to South America.
I have an older Garmin 550t that I used for hiking. I recall that I could get hike route files from just about anywhere and put them into the 550t; however, the base maps I did buy from Garmin.
So, if I use OSM with this new Garmin 770, does this impact my ability to work with downloaded routes and have full functionality of the unit?
Thanks for any advice. It about $600 with the back up camera, so I want to do this only once:
