Looking for some advice regarding my 4500 rds eon, Radio/Cd player, the radio works fine but when I play a cd I only get sound from the left front and back speakers. Would this mean replacing the complete new unit. When the car went in for its last service the mechanic at the main dealers said the obvious, it's broken, but I don't think he took the unit out and had a proper look. Said a replacement would cost in the region of £400/500. I have seen some for sale on eBay but thought I check all avenues before buying a replacement. Thanks for reading, all help and advice would be appreciated.
