Get Your Radio Code
Select a series above to see the required format
Opel/Vauxhall serials start with OP (e.g. OP670FW9002515). GM serials start with GM. Find the serial on the radio chassis sticker after removing from the dashboard.
How to Find Your Opel/Vauxhall Radio Serial
Method 1 — Radio chassis label
Remove the radio using Opel/Vauxhall release keys (or a flat tool on older models). On the side of the unit you will find a sticker with the serial in the format OP670FW9002515. Enter the complete serial including the leading OP.
Method 2 — On-screen display
Some Opel Astra G, Vectra B and Zafira A units show the serial by pressing and holding the AS (Auto-Store) button for 10 seconds while in code entry mode. The serial appears in two groups on screen.
Note: Vauxhall (UK) uses identical radios to Opel — the same OP-series serial applies. Select Opel / Vauxhall for both brands.
