any experience with PAC OS-4?

[AmazinglySmooth]

I really want a new head unit, but I need to have XM in the front while a DVD plays in the rear. It seems that the PAC OS-4 gives the nearest-to-factory experience, but I don't know if there are any gotchas. I have a 2011 Denali with two rear screens. Does anyone here have experience with it? How well does it work for you?

You need the this also unless they started including it. I have a used one I would sell if you want it.

How close to the factory experience can you get with the OS-4 and the harness you have used?

I used it and it works but it's slow/laggy. I had to get it when I had my Pioneer AVIC-Z110BT head unit.

Never had a problem with it in my Yukon.
