The Limited includes a multimedia infotainment system with 30-gigabyte hard drive and navigation system, Boston Accoustic sound system, rear view parking camera, UConnect wireless connectivity, SmartBeam auto-dimming headlights, and memory driver's seat. For 2010, the 4.7-liter V8 engine and the Overland trim have been discontinued.
