contact your dealer

CHECK ON YOUR SERVICE PORTFOLIO FOR THE CODE OR CONTACT THE NEAREST LAND ROVER REPRESENTATIVE AROUND YOU.

tahe out the radio call the dealer and tell him the numbers in the back of the radio will give it to you they night ask the vin number

You can't unless you have the VIN of the vehicle it came from.

If you have any service papers from the dealer, the code is usually listed at the top of the form containing details about the car
If you cannot find it, there are several sited on the internet that can provide the code
by your VIN number. The usually charge for the service

If you do not have the code in your purchase folder, the only way to get the player unlock code is from a Land Rover dealer.

This was done to prevent CD player thefts, since they would be totally useless without the code. The program has been highly successful.

There is no "factory" or "universal" code, so do not allow anybody to tell you that they can sell you one.

If you call the dealer ship they can give you the code and the secuence for the radio
