The Navigation is a Magellan Roadmate. This system is a OEM dealer upgrade. for $1099.99 at the purchase point for your vehicle you could have it added. The tray that sits on top of the dash is removed and the navi pops right in, it has a splitter into the radio and takes a total of 15-20 minutes to install. So far it has worked GREAT for me. It is touch screen with 3 user profiles and your passenger (or you...shhh) can use it while driving unlike many aftermarket ones. I paid $200 used but you can get a new one for 800-900 and a refurbed one on ebay for $350 range.
