I know that, but I read Android Auto itself is very buggy as well: people who have true AA in their cars, also experience all kind of issue's. The funny thing is, wireless worked better than wired.
The thing I particularly like about wireless AA, you don't need to mess around with USB cables. And you don't even need to take your phone out of your pocket, only before starting the headunit you should already start Google Maps on your phone.
Once the car is started, and Carlink finished connecting. Then automatically the route is displayed on your headunit, including autoplay of Spotify. I mean when it works it's great, but when it crashes during driving. Than its actually potential dangerous, as you need to close Carlink and restart it.
Only thing I don't really get, on my slow and not even capable of running native Google Maps smoothly. Android Auto was working better on that unit, as I didn't experience occasional crashes while connected to USB cable on that unit.
But other than that, on all other parts that Quad-Core unit wasn't very great. Only Android Auto was something, it did better: although displaying in a lower resolution.
