HI guys I have just installed an auto dimming mirror with a compass, the dimming on the mirror works really well (much better than the 2000 part did). So here is my problem.

The mirror originally came from a 2004 A4 and I am not sure the compass is working properly. I know the ones that were fitted to the A6’s required calibrating and I have the instructions to do that. However their I no button to press to calibrate the mirror. Has anyone dealt with the type of mirror that I am taking about and knows if it needs calibrating?

Thanks
James

 

That mirror doesn't have the seperate reset button under the bottom like the older ones do.
You should be able to just hold down the center button. The same one that you use to turn the auto-dimming off and on.
After 9 seconds or so a "C" should come up. Then you have to drive the car in a tight circle. After several revolutions, it show a direction.
