Update:
Well I never found an aftermarket Hitch to install so I went with the over priced factory unit. It took 4 hours to complete the project but it saved quite a bit of money over the dealerships install price. If you can turn a wrench and have a few larger metric sockets you will be able to complete this job. Just take your time to remove the exterior rear bumper so you don't break the snaps on the right and left sides and remember their are several 8 mm bolts below the satin black rubber step on top of the bumper. Once you have installed the hitch, just take it back to dealership to have the computer updated.
