How to reset radio / audio system

rexel77 · 03-11-2013, 12:37 AM

I have a 07 335 with nav. Once in a while after starting my car, I don't get any audio from my speakers. This includes radio, iPod, Bluetooth, or backup sensor warning. No audio period. Once this happens, the sound will remain off until the next morning. I was told by my dealer that the car does a reset after 4 hours or so which is why it works the next day. Is there a way I can force it to reset sooner?

Hold down the power button for 20 seconds or so to perform a manual reset.

My 1 series would that sometimes. I would unbuckle my seatbelt until the seatbelt warning came on. Once that happened, I had sound. In a parking lot of course!

some radios holding power and eject at the same time for 20-30 seconds will reset it.
