Hello I have a 07 335i with L7, the audio has completely stopped working. I can't use AUX or CD or satellite radio. This problem only occurred a couple times, now its continuous. all the Idrive says its loading CD drive and that's it.

1) Your battery is shot. In an 07 if you have not changed your battery
you are due. When the battery is low the IBS system can turn off systems
that it doesn't deem essential . Check the battery voltage.
2) The amp area gets wet and shorts out the amp.
Usually due to clogged drains or broken seals.
Check the amp area for water.

The Idrive reads (loading data from the audio device....) and it won't let me choose any audio options
