I know this has been posted a while ago but I just want to confirmed that its because of the LED reverse light. So during reverse the DAB signal loss, I saw the wiring diagram that the reverse light was actually inter-connected with the DAB. I tried changing with another set of LED light but the same problem. I further try to isolate the problem and found out that it was the right side reverse LED light was causing the DAB signal loss, when its the left side LED light is the only one installed, DAB would be fine during reverse. I tried to install a noise suppressor clamp on the right side reverse light wiring, no help. I stop at this, I don't usually use the DAB radio, I use more the bluetooth source so I just left both LED reverse light installed. If any one has sorted this out, please give a shout.
