my '97 manual says this.....I never could get mine to work though....but my adapter was 10 years old.....
CD Adapter Kits
It is possible to use a CD adapter kit with your cassette tape player after activating the bypass feature on your tape player.
To Activate the bypass feature,the ignition must be on.Turn your radio OFF.Press TAPE/PLAY and hold for 3 seconds.After 3 seconds,the tape symbol in the display will flash for 2 seconds indicating the feature is active.Turn the radio on and insert the adapter.
This override feature will remain active until EJECT is pressed.
dunno if this will work for ya...but I found it in my manual awhile back: )
