DVD Audio won't play through AUX function of Headunit?
 

Hey everyone! New to the forum.

I just bought my wife an 07 Uplander LT and it has the DES in it. We can not get the audio working through the head unit of the van. We read in the manual that after the DES is turned on that you can get the AUX (same as the CD button) that it should show "DVD" on the head unit and play the audio through the speakers. Nothing happens at all. Audo works fine through wireless headphones.

Any ideas? Is there an issues with the head unit? I probably wouldn't care to much but our son is only 1 year old and no way does he want to wear headphones.

It's under warranty so the dealership should fix it but if I can give them a heads up on what it might be I rather do that than take it back and forth to them until they find it.
