sorry about the generic response you got from the Just Answer bot.
If you have all the owner's books you might find the code on the first page of the service history book with the Pre delivery inspection information. There should be a box labeled audio with the code filled in.
If you do not have that follow these instructions to get the serial number and then post it here. I will try to get you the code from that.
1. Turn the ignition switch to ON (II).
2. Turn on the audio unit, and make sure you see COdE in the display. If you don’t see this message, remove the backup fuse for 1 minute, then go back to step 1.
3. Turn off the audio unit.
4. Press and hold the 1 and 6 preset buttons, then turn on the audio unit. The screen should display some numbers. write those numbers down and post them here.
5. Post the number you get here.
