I swapped sides on the CB and GMRS antennas today. Boom, no interference. I did notice though as soon as I provided power to the rear camera (which I had to disconnect during my rewiring) I got interference again even with the antenna on the other side, even when the backup camera wasn't "on." It has 2 12v inputs. One is the 12v trigger on the reverse wire, the other is switched 12v power to power it and so I can select the input and check on a trailer or whatever. So for now, I put both power wires on the reverse switch so I only have to worry about interference in reverse which is a non-issue. I might try a different camera later to see if that makes a difference and then I can wire it up like before so I can check a trailer if needed. Not crucial though.
