I've borrowed my nan's mini and she doesn't have the code for her radio so I thought I'd ask for your help!
Its a Philips and this is all the information I could get from it...
Type No 22 DC 652/60E
RG part no. XQD 10056
Digital Combi: 3BAND
FD 01 93 40 2281030
and the serial number (engraved into side) is RG52FP2281030
many thanks in advance,
