Hey up! I've just recently purchased an Astra Convertible 2003 model, which is fitted with the CCR 600 Tape Unit/CD Multichanger.
The problem I am having is receiving reception on AM stations. On 1089 (TalkSport) i can hear what is being said, but it is drowned out by really terrible feedback/reception issues. As silly as this sounds, it sometimes gets worse depending on how far i turn the steering wheel!!
I'm not terribly technically minded, but does anyone know of a quick fix before I take it to the garage to be looked at? For info, the FM stations seem to work OK.
