Had my new dash cam since Sunday but this fuzz just started this afternoon. But the way it looks does seem like what you’re mentioning. Some kind of nearby interference. I’ll see if taking the camera down makes a difference. Thanks for the fast replyThe only thing I can think of minus a actual fault with the truck is some sort of interference from a electrical device. It's possible a magnet could cause this also.
It’s been a few hours since the fuzz appeared and I was going to try removing my new dash cam to see if that is the cause but the fuzz is gone so I don’t think it’s the dash cam.Let us know if that fixed it. I had a weird thing with my display the other day that was similar...it eventually just "went away" and hasn't come back. I was worried at first that it was a bad cable connection to the display but I'm thinking some type of interference as well.
