I just bought a second-hand radio set, as mine wasn't working well. I've managed to connect it and it works well, except for the fact that it beeps continuously every 3 seconds and the beeps get louder when I raise the volume.

I also wasn't prompted to enter the radio code (which I do have) as the display didn't show the "CODE: - - - -" screen.

I have a VDO RD3-01
Model No: PSARCD100-01
VDAPSF30203555

I would immensely appreciate any help with regards to this problem. Thank you.

This stereo is often referred to as a "Married" or "VIN CODED" radio, as it does not have a normal security Code number, but is instead electronically paired to the engine management system of the vehicle it came out of, and as such cannot be easily transferred from vehicle to vehicle, even if it is the same model of Car.

When it is first powered up, it will communicate with the vehicle, and if this has been successfull, it will switch on and function in the normal way.

However, if removed and refitted into a different vehicle other than the original one, it will not recognise the encrypted identification of the new car, and you may find that the radio may not power up at all, or if it does, you may find yourself with an irritating beep every few seconds over the sound of the radio.
