So I didn't care for the Boss DVD/CD unit I had in there, which I mainly had purchased to to be able to use for a back up camera, well it sticks out to far for my liking because the screen needs to have room to slide out, so it's out.
So I picked up this unit:
Seems, pretty neat, has some poor reviews of slowness and some locking up from when it was introduced in the beginning of 2011. Kenwood has since released several firmware updates, once recent to this year, so that most likely will fix those issues. It also received other great reviews for what it is, and I got a great deal on it as well.
Nice feature, DVD, built in NAVI, rear USB input etc. With a separate cable, it'll allow all audio and video from the iPhone to play directly on the screen, pretty cool. Multiple A/V inputs and outputs.
Right now I've got the one rear camera, eventually I'll install a few more under the the truck for some nice views while offroading.
