How do you enter the radio code on a 1995 Volvo 940 turbo?

Just re did mine.when the radio is showing "code" enter 666 666 then push AUT botton.

If the radio is showing EEE.Try again.If the radio is showing "off".You will need to turn ignition to first position (make sure your lights are off) and wait for 2 hour for the security system to reset, then try again. Cheers, Wilf ....... gain88@xtra.co.nz
