Aftermarket Radio Upgrade

[Flytyme69]

I have looked around and can't find the answer I need, I have an 03 Expo EB with the 6-cd indash changer and rear seat controls, I do not have the overhead dvd system. i want to put in an aftermarket dvd nav unit and wanted the rear controls to still work and possible the dual zone system. Is this possible or do I need to not worry with it. Thanks

personally I dont think its worth the effort, you could "jerry rigg" up a steering wheel control kit (pac audio $50-$75) to the rear controls or just get a second remote!($20) the dual zone system will allow you to send video and audio to screens in the rear (if you have them) not audio in the front and audio in the rear. for example I play music over the stereo and I put on kids shows thru the dual zone so my daughters watch there tvs with wireless headphones, hope this helps

i believe the only way to do it is to go aftermarket to get the dual zone...i believe i can do it with mine
