I posted the below on the app forum and did not get any responses. Thought I would try here.
I am very satisfied with Google maps/navigation on the TB, enough that I will use my phone for navigation rather than using my Garmin 765. The only drawback for is the fact that I can not figure out a way to load a planned route, gpx file, from my pc and then select it with maps/navigation. I can get the file to the SD card but I don't have any ideas on how to make maps/navigation select it.
Thanks for any thoughts and/or help.
