My AVIC D3 unit has been installed in my 2005 Cadillac SRX for almost 5 years now. The rear camera stopped working about a month ago. When i either shift into reverse or use the rearview Map feature, I get a screen that says the image may be reversed instead of getting any video from the camera. I checked connections to the back of the D3. There appears to be good. Power, ground and video connections all seem good. How can i test to see of the camera is blown? I suspect this is the problem but would like to know for sure before i go ahead and order a new one. Thanks.
