I have a double din navigation system that has a full touch screen for any vehicle that takes double din stereos. It is a Kenwood 6017 unit that plays dvd's cd's and is able to do navigation and alot more as well. I also have a remote to go with this DVD player.
Other adaptions I have to this unit for extra is the following
Navigation system with voice activation (Add on unit)
I had this installed in a 03+ silverado and still have the bose and on star wiring kit along with the installation hardware. I also have an adapter to be able to use your existing steering wheel controls as well. This unit will bolt directly into a yukon, denali, escalade, sierra, silverado, and more 03+ gm chevy and gmc vehicles with no modifications.
To install in any other vehicle all you need is the wiring kit and the install dash kit which is very cheap.
$350 or best offer for the DVD player alone and can work out a deal if you are interested in the navigation or any of the other accessories or add ons that I have. Text me at 763-286-2730 and serious inquires only please.
