Assuming your talking about a double din unit, I installed my eclipse avn6600 in my 03 cavy. It took some work to get it to fit and look right but turned out OK. The newer issued metra 992003 dash kits come with a double din kit in it now, but i still had to cut some plastic behind the radio to get it to fit good. The hardest part was finding a place to tuck all the wires in the dash.
