2012 Factory Nav system

[dmac123]

Does the Factory Navigation system have an AUX audio left/right input such that a DVD player that has AUX OUT (line level) audio left/right connect directly with this input to satisfy the audio levels, etc?

Will it work?

Since my Tahoe has a USB port for an Ipod, I'm assuming it using another port on the Nav unit to input this signal, yes?

I just found out from my installer that the Nav unit for the 2012 model does not have A/V input on the rear. Have to use the front panel 3.5mm audio input.

Does anyone have a technical manual for the NAV unit they could post?
Not the User/Operator manual, but the one that shows the availabe connections on the rear. Or perhaps a picture.
