Hi guys. Can someone please help. Had my clutch sorted and now I can't use the radio. I bought the car 2nd hand without the manual, only the service book was in the car. I took the radio out and tried the number that someone wrote on the radio, but it doesn't work. The serial no of the radio is M238311 and the code written on it is 1624, I've even tried to enter the number from back to front, no luck. PLEASE SOMEONE HELP.
