Common questions answered

Volvo CR-… head units are unlocked by the diode configuration soldered on the PCB, not by a serial number.

  1. Remove the radio and open the casing.
  2. Locate the row of 12 positions labeled D1–D12 on the PCB.
  3. Check which positions have a diode physically soldered (small glass cylinder with a stripe).
  4. Select the model in the generator, tick the matching positions and click "Get Radio Code".

Thousands of Satisfied Customers

See what they say about our service.

Thanks so much for your help. In Spain, I was quoted 50 euros for the information I needed. With your service, I received my code in just a few minutes late on a Sunday. Highly recommend for the convenience and savings!

Isabella M.

Brilliant service! It was super easy to use at a great price. I got my radio working in no time with the code provided.

Alex R.

Fast and efficient, I made the payment (which was very reasonable) and almost immediately received the code by email. Service was going to charge me $55 and required removing the radio. Thanks to this service, I saved time and money.

Sophia L.

A seamless experience with exceptional customer support. The code worked flawlessly on the first try, saving me a trip to the dealer and a lot of money. The quick turnaround time for receiving the code was a game-changer for me.

Even though they couldn't resolve my issue directly, the immediate response and hassle-free refund process were very impressive. It's rare to find such honest and customer-focused service. Highly trustworthy.

Impressive service! Gave them my serial number and received the code in about 2 minutes, even late on a Saturday. This saved me not only money but also the time and hassle of dealing with service centers. Absolutely recommend!
