First i had a problem installing this Mirror.
Now i just finished the install and there is a sticker at the mirror saying ''Do not remove this until compass zone is set"
Then i got the mirror manual and it said " For calibration ,see owners manual" and as i live in Brazil and my car is euro spec,,how can i know my compass zone ???so i can set the compass of my mirror to work properly.
Anyone have a comass zone chart in the manual,,so they can tell me what is this compass zone here in Brazil?
