Audio System Troubleshooting
Unit Displays "oFF"
Any unit displaying "oFF" indicates there has been an attempt to program the unit with the incorrect code 3 times. To restore operation, turn the key to
the "ACC" position and leave the audio unit ON for 1 hour before attempting to re-enter the code. Or, the vehicle can be driven for the one hour period
with the audio unit on.
Note:
The "3-Minute Mode" will not work if the unit displays "oFF".
