I found a thread on the RL forum discussing an accessory backup camera from Acura. Scroll down for pics of it installed on one member's car. Retail cost looks like $325 for the camera and $175 for the attachment. It has a clean factory look to it but I don't know if it will fit our car. I think wiring into the nav screen could be done using the tvandnavtogo kit if the acura camera wires are compatable. I don't know the specs on the camera (CMOS/CCD, angle, etc) yet but I have contacted a dealer parts guy and am waiting to see what he can find out. Has anybody else checked into this?
