Hi, I have the Blaupunkt Cambridge M23 car radio/cassette which I would like to fit in my Mk1. I have had some help from a member to locate replacement belts for the cassette player. The radio has been bench tested and works fine but there is a problem with the cassette player. I am using a cassette which has a SDHC card fitted so problems with tapes getting in a mess is now a thing of the past. When the cassette is inserted the motor starts but the cassette does not lock in to the player. Is this a common problem? Does any member know of a firm that would be able to look at this for me and give the whole thing a service? Thanks
