Sorry to see the code didn't work.
I knew I had it somewhere .... after a rummage I have found in my old files a copy of the Service Manual for the manufacturer's (Philips) version of the VC 802, the 22DC711/77.
So far as it went your unit worked!! If you look at p4 you will see that WAIT followed after a time interval by CODE indicates the wrong code has been entered.
As said I didn't think a VC 802 was original to Hoe. In 1989/90 Volvo were fitting the SR-701 or CR-702's to the 700 Series plus the underdash amplifier.
I am wondering if you have pulled the unit .... if not and you do so you might be lucky and see someone has written the correct code on it somewhere.
Unfortunately my PDF of the manual is too large for the Forum systems!! If you DM/PM me here on the Forum with your email address I will send you a copy if you want one.
