I bought a radio code for a Rover R770 type, Radio / Cassette type number 22DC594 and the emailed invoice arrived instantly following payment. The website stated that for a Phillips type radio the code could take up to an hour to arrive and that the code would be automatically sent to the email address provided. Luckily I kept the website page open with the "Please Wait" displayed until the unlock code was posted there, which took an hour to arrive, so I'm very happy as the code worked perfectly and unlocked the radio. The only quibble is that the email that was then sent, didn't provide the code as stated that it would, but requested a review which I have now done, so make sure you keep the website page open until the code is provided there, otherwise you'll probably have to call them to get the code having shown that a payment was made as this did not come with the email. Overall though I'm very happy with the service as it does what it says it will do.
