Auto dimming mirror is currently working fine. But there is problem with the 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

On this vehicle, the "C" indicates circle calibration. According to Toyota, the following must be done:

1)Stop the vehicle in an area where it is safe to drive in a circle.
2)Press and hold the auto button for approximately ten seconds or until a C appears
3)At a speed of five mph or less, drive the vehicle in a circle until the direction is displayed

NOTE: There are certain elements which can cause this process to fail. The following is a list of things to check, but potential problems are not limited to said list.

A) The vehicle is stopped while driving in a circle prior to reset.
B) The surface is not flat.
C) The Earth's natural magnetic field is interfered with by such things as:
* Underground wiring
* Between large structures
* Nearby steel towers
* An open car door
D) There is a magnet or metal object near the mirror.

Let me know if this helps.
