I have installed a cd-changer in my W211 -04. The headunit is a Audio 20 and i have no phone installed in the vehicle. Now to my problem, when i put back the batterycable after installation the cd-changer work 100%. After a while when the radio have been off for aprox 10 min the cd-changer is totaly dead. I try to disconnect the battery again, no result. But When i disconnect the connector behind the Audio 20 an put it back again something happens. The changer works again! But it won´t do it for a long time, a new 10 minutes in off position and its dead again.

Does someone hava any idea what´s wrong?

Thankful for any ideas!

Sounds as if the wake-up line was not connected. Pin 4 of the connector Audio 20 (showed in attachment) must be connected to pin 3 of the cd changer.

Normally it's because the system needs to be version coded to include the changer.
