Humming from Rear-View Mirror Backup Camera Speakers
I think it is a Magnadyne M35 or M45TC, it is the one with the integrated backup camera, audio (don't use it), compass and temperature. We took a cinder block to the windshield (another story) and ever since I'm getting an annoying hum from the speaker on the back of the mirror. It is occasional and I cannot pin it down to something else, like raining, TV on or windshield wipers on. Thinking about getting a new one and calling it good but I'm not convinced it couldn't just be a loose wire or moisture. Not sure if I have a question, just open to suggestions or comments if anyone out there has seen this before.
