2010 GL450 Rear Seat Entertainment question
First off, I'm assuming it's a factory reat seat entertainment system, but maybe it was dealer installed? I've attached a picture of what the system looks like, found the picture on ebay but it looks exactly the same including the wireless headphones and remote.
Anyway, my problem. When I put a dvd in the Command system up front I cannot get it to play on the rear screens. I checked the manual, and I tried the dvd menu item labelled something like "active rear source" (can't remember exactly right now). It does play on the front screen in park. The rear system remote has an "input" button, which cycles between dvd - aux1 - aux2 - aux3. Dvd is the disc in the unit, aux2 is a disc playing in the opposite screen, but I don't' seem to have an input for video from Command up front.
When I put a dvd in one of the rear units it plays, but audio only comes through the headphones, I cannot get audio to com through the cars speakers. The command system "audio" menu has many sources, one of which is named "rear", but it's not working.
So, we've got a problem on long trips, I want to be able to swap DVDs from the front without stopping the car and have it play on the rear screens. Any help on this? Am I screwed? I hope I'm not screwed, the minivan I got rid of could do this easily and I would really stink if the Mercedes couldn't handle this use case.
