Bought and installed a Rexing V1P with 2 cameras. Works great and I'm still learning things. I didn't like their power supply cables and bought one from Frys for $8 to power it from inside the center storage between the bucket seats.
Removing any of the plastic was easy with the supplied plastic tool and stuffing the rear camera cable in the head liner on the passenger side was way easier than I expected. The cable I bought was just an USB extension so everything was just plug in and doesn't show.
