Dont know if this applies to your set .
Vauxhall Radios - radio works normally after entering code but display doesn't work
This often happens when a radio belonging to a car with a larger display (10 segment) is fitted to one typically with a small centre console display (8 segment). e.g. transferring the radio from a Vectra to a Corsa.
The CAR300, CAR400 and CDR500 can support both display types but it needs to be told which display type to use.
Here is how is done on a CDR500:
With the car ignition on, press and hold buttons 3 and 5 together and switch on the radio whereupon it will show either DISPLAY 8 or DISPLAY 10. Keep the buttons pressed until the radio beeps and the display will change from 8 to 10 or vice versa.
Release the buttons, switch the radio off and then back on and hopefully the radio will now operate correctly with your display.
