Get your serial from the screen
Bosch Screen Radio
Get your serial from the screen
Turn on the ignition and radio. Enter any incorrect code three times deliberately. The screen will lock and display your Serial Number, Device Number and Date.

Remove the radio to find your serial
Bosch Standard Radio
Remove the radio to find your serial
Use a flat-head screwdriver or release keys to remove the trim surround, then slide the unit out.

FAQ

Frequently asked questions

What vehicles have Bosch radios fitted?
Bosch units have been fitted to Vauxhall, Nissan, Fiat, Alfa Romeo and other vehicles. The 815CM serial prefix identifies a Bosch unit.
What does a Bosch serial number look like?
Most Bosch serials start with 815CM, but 905CM, 217CM and shorter CM forms exist too, along with A-series serials, the letter A followed by 9 to 13 digits. Labels sometimes print a space partway through, that is fine, enter it as shown and we will handle the rest.
How long does delivery take?
During our working hours, Monday to Saturday 8am to 4pm UK, most Bosch radio codes arrive within 6 hours of ordering. Please allow up to 24 hours for delivery. You will receive the code by email.
Do I always need to remove the radio?
No. For Bosch navigation units fitted to Vauxhall Connect and Nissan Connect systems, the serial is retrieved on screen. For standard head units, removal is required.
My code does not work. What should I do?
Check the complete serial. For screen-based retrieval, make sure the device number was also noted correctly. Contact us if the problem persists. All codes are guaranteed.
Is a Bosch radio code the same as a Vauxhall Connect code?
If your Vauxhall has a Connect or navigation system with a serial that includes 815CM, then yes, it is a Bosch unit. Use the Vauxhall page on this site for the full screen-retrieval guide.
Will the code work again after a battery change?
Yes. The code is permanently linked to your radio. Keep it stored safely.
Does the screen retrieval method damage my radio?
No. Entering three incorrect codes to trigger the serial display is a built-in feature on these units and will not harm the radio.
