Hello everyone. i am new to the site and new to Hummers.

I purchased an 04 H2. It has the LUX non touch screen.

I updated to the 05 touch screen and added the dvd headrest and rear view camera. I had to add the NAV tv box in order to get this working.

My questions is this. The guy that I purchased the units from says that he watched DVD movies on the dash unit. I cannot get it to read a dvd movie. It will read the NAV disc, a c.d. and the radio.

Does the o5 touchscreen play dvd movies???????
