    No warning tones/no audio/radio

    Just looking for some help if available. I have an F30 2014 Msport, Premium audio system. It does not have the Logic 7. Radio stuck in boot screen. Quit working completely. I could not even reset oil change indicator because time/date were incorrect due to locked up boot screen.

    Things I have replaced are:

    *(Screen) - Still no audio - Still stuck on Bmw boot screen.

    * (Din unit) - this fixed the endless boot screen issue. IDrive working now. Date set, oil change indicator reset. Time and date displaying in gauge panel now. Still no audio.

    *(Radio control faceplate) - still no audio

    *(HK Amplifier) --still still no audio

    *(HK ASD Amplifier) - still no audio

    I checked fiber-optic cable and it is good (Light passes from Com-Box to plug behind the head unit on both cables.)

    The red light coming from head unit to com box is not a steady light. It blinks about 1x/second. Is it supposed to be steady on? If so, what does this tell me?


    Does any of this stuff that I've replaced have to be coded to the car to make it work? I'm not sure what to do next. Any help would be greatly appreciated.

    Did you check the fuse?

    Yes. All of the ones in the trunk. Are there any related to audio elsewhere?

    Headunit must be coded.

    Did you ever determine what the issue was? I have a 2013 328i that seems to be having the same problem.
