E90 Head unit shuts off after 10 seconds.
The other day I started my car and after 10 seconds the head unit shut off completely, no lights or sound. (non-idrive) It kept doing this all day every time I started the vehicles. The next day it worked all day, and then today it started out working fine and when I switched my headlights from automatic to on the radio switched off and wont turn on anymore...What do you think this could be? still have to check the fuses but if one blew wouldn't it just stay off completely? Thanks for your help.
