[MTCD Android Head Units General] bzzzzzz:
Today is magically working again... it seems a very random behaviour because from yesterday I haven't touch anything on the phone or on the HU, and today is working (I'm sure it won't last long...).

Here the log of a call correctly routed to the HU speakers:

[MENTION=1423323]bobodaclownster[/MENTION] unfortunately rebooting the HU is not working for me, I've tried so many times. What head unit and bluetooth chip you have?
