Vauxhall


Please note that code entry is only possible with the ignition switched on, and in the order shown. If the display continually shows "SAFE" and a number less than "10" then the unit may be codelocked and will need to be left switched on up for up to two hours to reset before another code entry attempt is possible. If it does not reset after this time, or the display shows "SAFE" with no number to the left, then you are not following the correct code entry procedure, and your ignition has not been switched on. If all of your code entry attempts have been used up, then the unit will need to be sent to us to be decoded and reset, details of which can be found below.

If you have lost your radio code, the Security Code for this Radio is available NOW using our fully automated INSTANT RADIO CODE service. Once your Radio details have been submitted, your Code will be ready - Instantly !! - No Waiting !!

Removal of the radio is fairly straightforward. You may need to first remove the four small Allen Key grub screws in the front panel to expose the holes used for the removal tools. The removal tools are inserted into the four round holes at the sides of the fascia until a click is felt. The radio can then be withdrawn and the leads unplugged, although the cage and leads will probably remain fixed to the car.

Common Faults:

It is not uncommon for the removable display to fail or for only partial digits to be shown. This is often caused by fingertip pressure on the display when removing and refitting the display. The display is interchangeable between radios, and you may need your radio code number if a different display panel is fitted. The word "DISPLAY" is removed by pressing the "AS" button and entering the code number.
