Free Jaguar XJ X308 Radio Code

Every Jaguar XJ X308 from 1997 to 2003: which radio was fitted, where its serial number hides, and what we can do with it.

Your code comes from the serial number of the radio, not from the car — so the first job is getting that number off the unit. The table below is your XJ X308: the units fitted, and where the serial hides on each.

Already have the serial? Type it in and we will tell you straight away whether we can answer it.

Which radio is in your XJ X308?

Generation	Radios fitted	Serial	Where to read it	What we do
XJ8 / XJR 1997–2003	Alpine AJ9800, Alpine AJ2000W navigation-ready	JA…	stamped into the metal case (the label carries no serial); type the top line, starting JA	Free in 24 h, or instant if you pay

Radio names are what is written on the fascia, not the name of the company that built the unit — a “6000 CD” or an “RCD 300” is what you see in the car. Unit fitment varies by market and trim, so treat the list as the usual case and let the serial decide: it is the serial that determines the code, not the model.
