I recently fitted a rear view camera and monitor to my van. Straight after doing so I noticed my DAB radio reception had gone extremely poor. On disconnecting the monitor the signal
came back.
The monitor was a cheap Chinese one, I took it back to try a different model and the Dab signal disappeared again. I knew it was the monitor because the camera was still powered when I turned the monitor off. I was near another trader who sold expensive monitors, I borrowed one and this one didn't reduce my DAB signal. Sometimes you get what you pay for!
So If you are suffering a poor DAB reception, its worth turning your rear view monitor off to see if it improves.
