DAB Radio Signal and 12v socket

[nissandan]

Hi guys

Got a 65 plate Qashqai and the DAB digital radio signal is pretty good until my kids are in the back and turn on the in-car DVD player which is powered by the 12v socket in the centre armrest storage unit.

Any idea why this would cause this issue? FM/AM are ok just not DAB.

Thanks

Lots of things can interfere with DAB. I got some LED lightbulbs in my kitchen and the DAB radio in the kitchen went off every time I turned on the lights and I had to replace the bulbs.

You can eliminate a couple of things..

Get any DAB radio, extension cable, so you can put it in your car, see if the DVD players interfere with that one.

Try running the DVD player powered from elsewhere (they usually come with an adapter) with an extension cable so you can put it in your car, that would eliminate using the 12v socket as a problem. Actually if you have an adapter for the DVD players, just try playing them next to a DAB radio indoors.

Often items with switch mode power supply's can transmitt interference by the cars wiring loom and this is picked up by the radio. I purchased two power line adaptors for the internet, one of the adaptors power supplies was faulty and caused interference on the radio, the manufacture changed the adaptor.
