Most all these players will do everything except play a DVD movie on the flip out screen. Most of these have video outputs for rear passengers that can watch a DVD while driving. You are correct about the parking brake wire having to be hooked up. But it is just for the built in screen that comes with it. Navigation, CD, AM, FM,XM and all the rest of the features would be pointless if you had to pull over and set the park brake to use them.
The one I would recommend is Pioneer's AVIC-N1. I've sold/installed a handful of these pieces and they are wonderful. It has the most features for the money and well put together, including touch screen, vehicle status (speed, tach, g-force, etc) are all part of this unit.
