On a road trip and the speakers decide to not work. Only two in the back working. How do I fix this? Resetting pivi not working

 

Visit your dealer.

 

It's a bug. Switch it off, get out of the car and lock it. Wait for 5min and see if it is fixed. Someone here said it was a bug with the bluetooth/airplay and media playback.

Mine dose this all the time. Ive noticed it happens when I'm loading the car and having my phone go in and out of range for the wifi Airplay.
