How to find your Audi serial number

The guide below will show you exactly where to find your Audi radio serial number.

Audi Chorus / Concert

Remove the radio to find your serial

Insert the four radio release keys into the corner holes of the fascia and apply gentle outward pressure. The unit slides forward. You do not need to disconnect any wires.

The serial is on the label on the back of the casing, starts with AUZ, 14 characters (for example, AUZ2Z3C1420538).

Audi Symphony

Remove the radio to find your serial

Insert the four release keys into the corner holes and slide the unit forward. The serial is on the label on the back of the casing, starts with AUZ, 14 characters (for example, AUZ1Z4H7755256).

Audi RNS-E Navigation

Find your serial on screen

You do not need to remove the unit. Power it on and look at the bottom of the display, the serial number appears along the bottom edge of the screen.

It starts with AUZ, is 14 characters long, and the sixth character is always 7 (for example, AUZBZ7H7145296).
