RNS510 no FM or AM

**night_flight** · 18-09-2023, 07:40 PM

Recently my AM and FM stopped working. Signal quality indicates 'poor' when holding setup button, but if it was the signal poor, should I at least be able to hear static FM? I am not sure is it the antenna or a faulty unit....bluetooth streaming is fine..

These RNS510 units are getting old and seem to be starting to fail or play up. It might be time to look into upgrading the unit to a RCD330 with Apple Carplay/Android Auto.

Im sure one of the electronics gurus on here will have some advice for you.

Have you pulled the radio out of the dash and had a look at the aerial connection? It may be loose/damaged after years of use and movement/bouncing in the dash as a result of the movement of the car.

I have not but will check... As I dont have a shark fin unit antenna on my car, could it be that maybe the antenna broke somewhere at the back? I would also assume that if the antenna was damaged there should be some AM radio pickup...

Arent the aerials for radio embedded in the windows at the rear

MKVI onwards I believe. MKV have the roof antenna.

Seems that there should/might be more to the antenna problem than we might be told. Wondering if the head unit has been removed recently, or maybe under/behind dash work done which may have dislodged/damaged the aerial wiring. Need more background info from the OP.
But, I agree with previous suggestion, remove the head unit and check the integrity of the antenna connection.
