Philips Car 400 radio code
 

Cheers!
Looking for radio code for Philips Car 400
The car in question is an Opel Vectra B '99.
GM0400X2230343

Try code 3xxx full code pm

Hey, thanks for the fast reply, I just came back online after trying to input the code but this is my first time doing so correct me if I'm wrong but I need to turn on the radio while holding the AS button and it should beep and prompt me with 4 dashes(----) for the code right ?
Tried it several times and it always shows me "SAFE" message on the display, no number next to it and no dashes for the code.

Must be in the car with "IGN" switched "ON" while holding "AS"

Forgot to mention I tried like that yeah, found some info that I might have to turn on the radio and wait some time before I can try inputing the code but don't really understand it because I still have to turn it off to turn it on with the AS button?

1/ Turn IGN on and radio OFF
2/ Press and hold "AS" and turn on radio

If wrong codes entered then you will need to wait for "xx----" upto one hour (xx=number of tries left)

Followed the procedure but it still displays only "SAFE", as if I just turned the radio without holding AS.
Could the radio be locked?

Must wait upto an hour
