how i will do to conect in front any dvd
my GL is fitted with comand with tv tuner and reversing camera that i see is AV 1

If I understand your question, in the 2008 and earlier GL's, you cannot play a DVD by inserting it into the COMAND unit and you cannot watch a DVD on the COMAND screen (from any source). You have to use the DVD player under the rear passenger's seat. You can, however, hook up an external DVD player or video source to to the rear DVD unit using the AUX1 and AUX2 inputs.

Substantial changes are being made to this setup for MY09, I believe with the relocation of the DVD player to the COMAND unit and the ability to watch DVD's there.

i find the solution on comand
in the front unit comand is write av2
av2 is located under the spare tyre in trunk
there is a tv tuner
that have av 1 and av 2
in av 1 is reverse camera
in av 2 is free you can plug there a extension cable were to plug any ext source audio and also video

Good find! Can you post a photo showing the location of TV tuner and part number if you can see it? I wonder if US GL's have that as well...

Thanks!

Nice, I'm intersted to find out more about this too.

Bump any update to this
