Vectra CCR 600 multichanger code input help

[Mark Dootson]

Hi
I didn't get the Audio handbook with my 99 vectra but I have all the
relavent codes, can anyone tell me how to input the code for the
multichanger (not radio code).
I've had a look in the audio handbook for my previous vectra (95) but it
only goes up to the CCR500.

Regards
Mark
