How to find your SEAT Leon radio serial number

Where it is

On the label

  1. Check the radio card in the handbook wallet first.
  2. Otherwise take the radio out with radio removal keys.
  3. Copy the serial from the label: 14 letters and numbers starting VWZ, AUZ, SKZ or SEZ.

Photograph the label rather than copying it by hand — 0 and O, 1 and I are easy to mix up.

RADIOPush both keys in until they click, then pull the radio forward

It comes out with a pair of radio removal keys. Which keys, and where they go: how to remove a car radio.

Tips for your SEAT Leon

  • Mk2 radios are double height, so four keys.
  • SEAT supplied a code card with the car — worth checking the wallet first.
  • Type the serial exactly as printed, including the SEZ at the start.

No. From the Mk3 the radios are matched to the car.

Can you do every SEAT Leon radio?

For 1999–2005, 2005–2012, yes: the code appears on screen as soon as you have paid; for 2012 on, not at the moment. The free check tells you which yours is before you pay.

It depends on the year. 1999–2005 (Leon Mk1): Aura, Adagio and Alana radios. 2005–2012 (Leon Mk2): SEAT MP3 radios, RCD-type radios and RNS sat nav. 2012 on (Leon Mk3 and later): Media System touchscreens. Radios were often swapped, so the serial on yours is what counts.
