Hi there, my galaxy just came back from the garage and after changing the battery, the radio is asking for a code. I have entered the code in the log book but the radio then just says 'wait 30'. I have carried this out 6 times now and no use. Does anyone have any suggestions? Could this code have been changed by a previous owner? and, if so, how can I reset it? Any advice would be gratefully received. Many thanks Lee
