Auto dimming mirror is currently working fine. But there is problem with compass getting stuck with letter C. I know it is meant that to calibrate this compass. Could you tell me how to calibrate? Or something happens? Thanks.

It sounds like you have a fuse out, lets start there first.

Here is a guide and some diagrams (below) to help you get the job done:

If all fuses are okay I would remove the negative battery cable for five minutes and then reconnect. This might reboot the system.

Please let us know what you find. I'm interested to see what it is.

Cheers, Ken

No luck at your method. Any idea is much appreciated. I need to calibrate the compass tonight and then let you know the results. Thanks
