My radio signal is rubbish

[newsh]

Do you know which wire powers it because I've been messing with my wires to get a ignition feed

Does your car still have its ISO connectors?

A5 goes live when radio is switched on. I *think* it’s a white wire in the car but not sure.

Yes the aerial is powered, switched on by the radio. They do go wrong when water gets in. Or sometimes after a thunderstorm.
You can access the aerial base by removing the rear dome light to measure if it’s getting power. There’s a small spade connector on a white wire?
I need to change the one in my RS4, I can only get a couple of really strong stations, radio 2 and 4 here at home I think.

Also have the same issue, it's another job on my to do list.

I've lost my radio signal all of a sudden...it was fine 2 weeks ago but all of a sudden stopped ...the aerial is pushed in OK at the back of the set .
Is the aerial powered on these cars
