Backup Camera Audio Noise

The audio of my backup camera has started buzzing. I really can't hear anything from it any longer. Up until just recently, it worked perfectly. I did recently have a new roof installed, and have added a new 25wt solar panel on the roof to replace the old 5 wt panel that no longer worked. Is it possible the new solar panel is creating some sort of interference? I did notice the problem at some point after installing the new solar panel. Not sure if it worked after that install or not. I guess my first step is just checking the connections, but beyond that, I really don't have a clue what is going on. I guess it could be a microphone failure. I assume it is part of the camera. Just looking for some ideas or to see if anyone has experienced a similar issue.

Turn the volume down. Why would you want the volume up when going down the road anyways. You will still have a good picture of your toad.

Not really the issue and really doesn't even address the question. I didn't say I was going down the road. I do turn it down except when using it for backing in. But I can't use it at all now because of the buzzing.

Often audio noise is the result of a poor ground on the shielded part of an audio wire. Try just giving a wiggle to the connectors on the camera and monitor. If that does not fix/identify the problem,perhaps it could be electrical noise created by/from the charge controller which converts the output voltage from the new solar panel(s) to system voltage. To test, temporarily unplug the the connector at the solar panel or lift one side of the connection at the charge controller. Good luck with it.

Thanks Tom. I hadn't thought about a grounding issue. I'll give that a shot. I do have the solar panel wiring run through a dash switch so I can shut it off if desired for service and that doesn't make a difference, nor does it matter if its dark outside - noise still present. I'll check the grounds. That makes perfect sense.
