the clock is set to 24 hour or military time, I can not figure out how to change it to 12 hour time. The owners manual doesn't say anything about military time. can you help me. Linda Hutchinson

The attached is all we have. I would think once you have set the correct time it would ask you 12 or 24. Try changing the time to a different time and see if you get the choice. Then change it back to the correct time.

It does not ask or give a 12 or 24 time mode choice. I have tried the instructions several times and it does not work. Any other ideas ? lhutch64

I don't but I have given this to another technician to assist. If you don't hear from them then reply back to me.

The last option is to talk to the service department at the dealer.
