I need the four digit code for my brothers car radio/CD player. It is in a Seat and the model of the radio is Alana.

The serial code seems to be:
SEZ2Z9E3142312

It is etched into the side of the unit and also on a sticker.

I can provide any other info required because I have photos of any markings on the radio.

Hopefully someone can help.

Cheers.
