I have played a bit with forescan on mine, and I don't think there was a way to overwrite the camera at higher speeds. I gotta look for that one.
I am pretty sure you can set to type in an address even when moving. That is stupid annoying they do that even for passengers. I dunno if thats an android auto block or truck one. The truck address screen I think you can overwrite, but if its Waze with Android Auto, I think thats a block in AA and not the truck.
