I have the clarion VRX935 VD the thing is pretty sweet. I have a PS2 hooked up to it as well. There are a few brands out there that some like more than others. Just to name a few Clarion, Alpine, Kenwood, Pioneer. I personally do not like the pioneer unit, it have a gyroscope in it for the montion detect, which trying to by-pass will void the warranty on the unit. The alpine units have awesome screens they have the touch pluse to let you know your selection was accepted witht he touch screen, down side is getting to the screen while driving. You need a toggle switch and flip it on of on off on off on... However there is a flip switch they sell something like 50 buck that will do this for you.. Kenwood's new double din if you have the room for it is a great unit, has the navigation, touch screen, dvd and camera input options. If I ever get rid of my clarion this wil be the unit I am going with. The bypass is as simple as grounding the saftey brake wire. Clarion I have had this unit for about 2 years now with no issues, touch screen,dvd, and flip screen. One of my biggest gripes with this unit is how far out of the dash it sits. The bypass again was just ground out the brake switch.
