I have a F90BT and I installed a reverse camera on it about 2 weeks ago. The camera worked perfect for about a week but one morning I got in my truck to leave and put it in reverse and the image was all messed up and snowy looking. I checked all my connections and that was not the problem. Every once in awhile it will come on and the image will be perfect but other times it does this. What could be wrong? Also when the image looks like this the warning that says "Caution Image may appear revesed" will come up and go off several times like the radio is loosing its connection with the reverse wire or something. I have the PAC OS4 so the reverse wire is connected to it. Could the OS4 be going bad?

Thanks

well yes the pac could be going bad, but that would not affect the video quality, that will either be a bad camera, bad avic, or a bad cable.

try plugging something like a home DVD player into the camera input and see if it is clear to rule out the AVIC.

Try covering all your RCA connectors with electrical tape, even ones that are connected to something. You could have one of them hitting something metal and grounding out causing interference.
