I recently upgrade the Nav unit up front (Found an E7006 for $100!) and would like to do the rear audio upgrade for the kids. I'm assuming the cable up there for the audio is different than the stock cable for the vans with DVD. Is there a plug and play option for this? Front nav upgrade info was in abundance, but rear dvd upgrade has been hard to find.
Alternatively, would i be better off two just get an aftermarket unit? I would like to retain the 2 zone audio function. Thank you in advance.
