well just for some change then why not try out the clarion. saw in a friends car and it looked nice. touch screen is a pretty cool feature. i cant tell you much just because i only saw it for a little while. my .02 cents
My .02 = touch screen, while it's a nice feature, is just another thing for people who ride shotgun to mess up.
The JVC is an interesting HU, and the screen is actually quite nice, but I think the Clarion is the better of the two units, as far as tuning and SQ is concerned. If you want to watch movies, and have people stare at the headunit all day, the JVC is the way to go.
