I agree with the aftermarket parts. I've had my eyes set on a $2600 setup for almost a year now. Haven't gotten it becuz I was more worried about performance parts first. I wish I could find the invoice to the parts I ordered but I do know that its a touch-screen Kenwood dvd/cd/bluetooth/stereo/nav with back up camera and all new speakers throughout. Daymn...now I'm getting excited again haha..I need some money
BUT yea...factory navi looks probably the cleanest but aftermarket has better bang for the buck!
