I have a clarion 815, 7 inch motorized touch screen with internal cd player, dvd player in the glove box and 2 6.5 inch flip downs right behind my sun roof.. The Touch Screen is the way to go.. actually makes the system easier to use instead of just looking cool... and the look on people face when you start tapping away is great..

99 SVT with resonatorless exhaust and open element intake
