I have one in my 06 and I love it. It was the newest one that was out at the time April 2006 Manufacture date. It does have some updates over previous models, such as displaying more street names, and NAV audio only coming from the drivers door. The latest NAV disc from MOPAR, surprisingly had more sub-divisions on it. You can pick them up on ebay for around $600 bucks give or take... I picked up a NEW 6disc Mopar 6 Disc rear CD Changer for 75 bucks shipped to my door... I think it is one of the best investments I have made on my Jeep (cept for my Renegade Light Bar)
