My understanding is that it hijacks the USB input so it's just another 'source' everything else is intact. There are some obvious/not-obvious pieces of that, that you can't use satellite radio with it at the same time as they're separate sources, but anything within the android OS should work simultaneous...e.g. you could use SiriusXM App with Google Maps@plars ive been looking at a tesla-style update, but its looking like more of a pain in the ass than its worth. is this unit basically updating the factory unit with a separate brain to provide control? i am a little confused on how this set up works. it looks like it would keep everything stock, just update the functionality, yes? looks like a killer deal!
