When I bought my new GTD it came fitted with the standard RCD310 (non DAB). I've subsequently fitted an RNS510. The RCD310 has been sitting in a cupboard gathering dust ever since but I am now thinking of selling it. Looking at eBay it is probably worth £40 to £50 max. I don't have the code for it, so would need to get this before I sold it. I understand that I should be able to get my local dealer to tell me the code free of charge. Has anybody got any experience of doing this? Do they need to inspect the vehicle/radio? Does the radio need to be installed in the car for them to do it?
Basically, is it an easy job to get hold of the code or should I just save myself loads of hassle and keep the RCD310 under the stairs in case I need to refit it to the car one day?
