Jaguar radios unlocked online in minutes — your original code, calculated from the serial number.
For your Jaguar radio code we need the full serial of the unit. Alpine units from 2001 on carry a 14-character label starting JAC, such as JACN2071152445. On 1990s units (XJ X300, X308, XK8) the label has no serial: it is stamped into the metal of the case, starting JA, such as JA0425S0728192. The Jaguar code card prints an 8-digit radio serial. Type the whole number, not just the digits at the end. Ford-built units fitted to some models use M or V and six digits.
Two lines stamped on the case? Type the top one, starting JA. The shorter line under it repeats the end of the same number.
Getting at the label takes two tools: something to pry with and a Phillips screwdriver. The trim around the radio is held by clips — lever it off, then take out the four screws that hold the unit.
14 characters, starting JAC:

XJ X300, X308 and XK8: 14 characters, starting JA:
JA0425S0728192
The card from the handbook pack prints the radio serial as eight digits:
