I got the Avic F700BT and knowing that it did not fit into my 2005 Ford Escape went ahead and did my own install. I need to find a DDin kit for it that will keep it secure. I found what was supposed to be a kit for fords at circuit city, but the trim is too large. Anybody with ideas?
Check Metra's website
i'd look up ur car on metra and see wha they recomend. if not you might have to dremmel that bad boy you already got from CC=) my kit worked fine but for w/e reason the 07 & up jeeps with factory double dins have a metal bracket in the back to hold the stock HU in place. that being said any other unit on the market is larger then the stock HU lol so to get my F90 to fit me n my buddy had to whip out the dremmel and saw out the metal harness out of my dash to do so... lol HUGE pain in the ass. 
Played hell finding a retailer but am going with the Metra- 95-5817 Am working on getting a piece of banding to ensure you can not pull out the unit.
