i'm not a big fan of video in cars, but this is a good unit. it plays mp3's and even dvd+r's (i've tried //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif ). the motorized screen works great and is pretty sturdy.
my local shop sold them for $1600 new, and closed there last few for $1200. at the price, they are worth it in my opinion. clarion makes a good product, you should be happy with it.
It's a nice unit but make sure you save your reciepts. My flip out motor failed on it and I can't find my reciept. //content.invisioncic.com/y282845/emoticons/verymad.gif.3f39c5c2fd57527b671fad3efdfac756.gif
