I tried to simulate everything while I'm waiting for the dongle to arrive and this is my concern:
I plug in the phone and then start the car. It takes about 15 sec for the HU to wake up and sort out.
However, AA does not start automatically. I need to unplug the phone and plug it in again for the HUR to register AA connected.
How's that working for you? Does HUR recognize AA right away?
The dongle is redundant if I will have to plug it in every time I start the car...
