I have a 2006 Jeep Grand Cherokee currently w/o nav. I just ordered the replacement nav bezel and that should be in shortly. I want to install the D3 with the bypass. Has anyone installed the bypass on an 06 Cherokee and how exactly do you do it? Thanks!

it's no different than doing the bypass in any other car.

Cool...just found the flash tutorial as well to help. Any known problems with hooking up a PS2 or XBOX as well?

both at the same time will require a video switcher.
