Hello all I have a bit of an issue with a C5 I have just bought. Its a 2006 LX newer shape and has the basic CD/radio system. Problem is I cant disable RDS on the radio so its keeps jumping stations. I have pressed menu gone in and made RDS inactive and pressed OK and RDS goes off but it comes baack on itself if I change radio station or turn car ignition off . Any ideas I also seem to get a series of beeps from the radio when turning ignition on? bit stuck.
