I'm planning on putting 9" screens behind of the front headrests of my 2007 Sierra HD when it comes in. One of those will have a built in DVD player. GM has a two head unit options available. One can play DVDs and the other can't but it has voice recognition. The one that can play DVDs probably can't do that while the vehicle is moving. I presume there is a way around that? I wonder if that can be used to feed the rear screens so I won't have to get a second DVD player if I don't want to.

In the end it will probably come down to if I want to use voice recognition or have a DVD player up front.

Any suggestions and/or feedback will be appreciated.

Thanks!
Tom

You can do (2) dvd players in the glove box and 7.5" headrest monitors for less than the factory option. Around $1100 installed at Best Buy.
What do you do with the voice recognition?

What do you do with the voice recognition?

Swear at it when it doesn't understand what I said

This is what I need the factory head unit to do -

Accept input from a backup camera mounted near the hitch
Accept input from a camera mounted on the back of my car hauler
Accept input from the DVD player mounted in the headrest
Accept input from an X-Box

Ok, I just answered my question after typing this. I'll get the cheap head unit and go with an aftermarket one. The factory won't be able to do all this. So now it will be a toss-up between the Kenwood and Pioneer.

Also keep in mind a video source selector, you can get them from 2 sources up to infinity

Tom- yes there is a fix for the 2007 radios that will let it play DVD's while movng. Plug and play. Im sure it could be easilly wired up so it outputs to the aftermarket screens...I know youre up in massachusettes...maybe I can come up and mess with it to get it working

I keep trying to convince my dad to trade in his '03 tahoe on an '07 cause I want to start taking apart the GMT-900's and figure out the insides of them.....im bored with taking apart the -800's. ):h

IIRC the dvd head unit also has nav and voice recognition. The DVD head unit has to be orderd with factory rear seat entertainment. Also, all of the new nav head units have the provision for the factory backup camera. Ive looked at most of the -900 wiring schematics and pinouts and it would be pretty easy to add the factory backup camera to a pickup truck nav unit (the factory backup cam is only availible on the tahoe's and burbans)

the factory DVD head units also have wires for video out that look to be in standard sheilded composite video form. All you'd need to do is some wiring and stuff to turn it into the familiar universal "yellow" video plug that would work with the aftermarket screens. You might need a video distribution amplifier tho; I dont know how much gain is on the factoruy DVD head unit video output.....

Thanks for the info! I completed my order just after my last post. The place that does my A/V installs is closed for renovations. I haven't been able to get ahold of anyone over there and I had to make a decision now (I don't like waiting ). I went with the head unit without navigation. My '05 has the Kenwood unit. I'm really happy with that but always like the latest and greatest. I'll see if they've updated that over the last 2 years. The new Pioneer is supposed to be pretty nice too.
