I have an 07 X5 3.0 with no sound out of the radio, but all functions seem to work... if i press the volume button, it gives the mute symbol, but if i turn it up, there is no bar graph to indicate that it is going up in volume, but not sure if it is even supposed to do that...
Also no door or light chimes ...
It is the regular radio, not the good one.

Also, the key fobs rarely work, even if i leave them in the ignition, it does not have comfort access...

Any help would be greatly appreciated...
TIA

Check all fuses under the glove box and in the rear hatch. Or it could be something related to your amp. Open your hatch, remove the cover on the left side. The amp is the bigger of the boxes. Are you 100% sure you don't have the DSP HiFi? Run vin and look for S677A HiFi System Professional DSP. If you have DSP, any bad/not powered fiber module could take the amp off line.

I actually checked all fuse in both boxes, and the fuse in the amp.... the number on the amp come back to standard system...
I unplugged connections and checked for bent pins or corrosion..
does the singal for the chimes and turn signals go into the headunit, or directly to the amp ?

Thanks
