doesn't android auto also depend on BT? not clear to me why, but I believe it has to be on.

in any case, I find Android auto just trades one set of issues for another. voice control is kinda iffy for all but the most unambiguous commands. I also experience deadlocks at least once a week that require restarting the head unit, phone, or both. I've had this issue with two different phones in two different cars. not sure what the root cause is, but it is really distracting when navigation freezes halfway through a trip through an unfamiliar area.
