Please help an extremely non technical person.
I get poor reception on FM radio and bad interference when air blower is on.
I have a Grundig 6 CD changer fitted.
Any ideas?????????????

After market stereo. Lots of Bravo's have this problem and the only reason I don't have a issue with it is that most Radio stations are utter dross and sound better with interference.

Shabash!

Sounds like your aerial connection has fallen out or is broken somewhere. Take the radio out and check that the aerial plugs in securely.
