I just installed one in one of our Sema Challengers this passed October. Very nice unit! I like it because it is very well layed out and simple to use. If you need a no-frills, easy to use unit, this is a nice one to use. My only issue with it is ejecting discs. On my Alpine W200 (in my personal car), when you press the open/eject button, the monitor slides open and the disc automatically ejects. With the Clarion, after press the open/eject button, you have to press another eject button that is behind the monitor, next to the cd slot. Minor issue, but just wanted to be honest about it! Good luck with your decision...
