I have the complete NAVTV setup with the rear view cam in the roundel. Installing the camera in the roundel is not difficult at all. Since the emblem is made of plastic, it is fairly easy to cut using a dremel tool. The camera comes with a small washer nut which screws over the emblem. Done! What took time was cutting into the metal behind the roundel. It depends of course on the depth of the camera and mine was just hitting it a touch so I had to cut a hole. The metal was SOLID and took time to cut with a dremel tool. I would use a hole cutting saw/drill if I was to do it again. Once I cut the hole, it was easy to run the wires under the plastic panels in the trunk liftgate. Wiring was a little tricky but not difficult if you know what you're doing. All you need is a relay that switches with the gear in reverse.
Works good but the camera from NAVTV is not the best out there, but it's not bad either. In sunny conditions, the pic is very bright but then again in low lighting it's very good. I haven't had a chance to compare it to others but I found the lexus cam to be very good. Let me know if you need any help.
