Citroen Xantia Radio problem?

The theftlock function of the radio has been activated.

There are 2 kinds of the theftlock function:

1. PIN-code. The radio requests a PIN-code after the power has been disconnected.

2. "Electronic marriage". The radio has the car's VIN number in its memory. If the number mismatches, a frequent beep sound is heard. The VIN number can only be changed using a EEPROM programmer or a dealer's equipment.

I think yours has the PIN-code as you can see 4 dashes on the radio display.

I think you're unable to enter the code as an invalid code has been entered several times.

To reset the radio unit, you should leave it turned on (showing 4 dashes). After 2-3 hours, the dashes will start blinking or the display will change to '0000'. Now you can enter the radio code. Be careful, after a certain number of invalid attempts it may lock up permanently.
