We bought a Nissan Qashqai second hand, but lost the radio when the battery had to be disconnected. I called the local Nissan dealership and was told I would have to take it into the shop so they could remove the radio from the console and look for the serial number on the back of it - this would likely cost in the region of £140 if I remember correctly. I thought there had to be another way, and that's when I came across Radio Codes UK. For a small fee and by pressing a few buttons on my existing radio, I got the codes I needed and my radio returned for a much more reasonable price. A very happy customer, indeed.
