View Full Version : RCA Inputs But No Rear Ent. System?

02-23-10, 09:40 AM
I have an 08 EXT (Ultra Luxury) has everything but rear seat entertainment and power running boards. It has the Red-White-Yellow RCA plugs in the back but no entertainment system. Does anyone know if these work or are they just "dummies" for later install?

I have tried to get these things to work, It seems they only work for the rear seat audio with headsets?

The audio will work if you choose AUX on your Nav screen, but video will not show up on your main screen.

Looks like I am gonna need to get the Coastal Tech GMX-322... this will give me the inputs I need.

I read somewhere on the forum, you have to go to the dealer and get a u42 upgrade on the system, then the video plug will work...

have anybody done this????

They are now standard on the 2010 even without rear seat entertainment, and they work on my 2010, I tried my iPod and it worked, but with the USB port in the center console I use that. :)

Has anybody got that u42 code upgrade from the dealer? and then try out the video input in the back? Does the video feed into the aux?

wish i got the 2010....:-(
