For the last few weeks, I'm suffering from very poor reception on all FM stations after previously being nigh on perfect. Radios 1 & 2 are only showing the frequency, rather than the station name. The only thing I can think of that might have caused this, is that I had the Battery off the car a few weeks ago for a trickle charge. Is it possible that on reconnecting the Battery, I have blown a suppressor?, or could there be another cause?. Because the H/U hasn't been touched, I haven't removed it to check the aerial connection.
