Yet another dipstick who did not check to see if he had the code for his car radio before replacing the battery!!!

Model R670 Radio Cassette fitted in a Rover 216 Gsl.
Type No. 22DC670/60E
ARG Part No. XQD 10003

Not sure which of the following is the serial number;

WA 059115

AR670WB8132605

So any help with locating a code would be great.
