Look into Panasonic CQ-VAD7200U or CQ-VAD9200U
Both are comparable to the Clarion unit but w/o touch screen. 7200 is actually more like the Clarion but plays MP3 CDs. The 9200 unit has a center channel amp built in and 5.1 digital encoder built in..in which the Clarion has it but has to be bought seperately. I got the 9200 version but haven't installed it. Bought it for $1700.
