FYI: there is no "nav" bezel from jeep for the 2011 models, because they made the basic radio and the higher navi radios the same exact size.
For the 2008 model compass there is a navi bezel part from jeep # 82211589 and you need also need to get the METRA 99-6510 for a double din radio. I only buy the pioneer avic-f700bt or avic-f900bt or avic-x710bt or avic-x910bt navi systems for my cars (from ebay). They can cost $300-$550 depending on what model you get (and not $2000 from jeep). I'll be posting the install photos and parts list shortly in a new post so you can see how it looks in a 2008 compass.
