MB COMAND 2.0 head unit replacement. HELP!
I have bought a Joying Android head unit (7 inches double din) to replace my COMAND 2.0 which appear to be fiber optic, on my 2002 ML 55 AMG.
When connected via teh provided ISO harness, the new head unit powered up nicely, but no sound came out.
Is there any way of adapting the fiber optic system to the new head unit without having to re-wire everything?
Help much appreciated.
Pierre.
