Unlock code needed for car radio Philips CAR400

[RegWorts]

Hello

Can anyone help? My car battery had to be replaced and I can't find my radio code. The serial number is GM 90 506 173 and the radio is in an old Vauxhall Astra.

Quote ALL the LETTERS+NUMBERS on ANY BARCODES , LABELS or STAMPED IN THE METAL CASING.

There should be a 14 character Serial Number beginning with RG or RN or PH or GM or similar
