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?
Standard Bosch serials begin with 815CM. Navigation units may display the serial on screen after entering incorrect codes three times.
How long does delivery take?
Bosch radio codes are typically delivered within 60 minutes of ordering.
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.
