The Android stuff takes patience, TRUST ME. I've had mine for a few months and I just got it the way I like it. I haven't started play with the GPS though, that stuff would really get confusing. Normal GS is easy, but with this stuff I can make it track the way I'm driving and if I pass a certain waypoint I set it'll automatically route me to a destination. For example if it sees me getting on a freeway that I always take home, it'll automatically set up a route going home...accounting for traffic, construction, etc.
Will I ever set that up? I dunno, lol. I kinda wish I knew someone with a name brand A\V receiver so I could play with it and see what all they can do.
