hi all, I have a Canadian model 04 M3. I know the auto wipers function makes the compass not work, but was wondering if I could some how just use the mirror autodim function. Bot sure how to even remove the mirror. I bought the mirror off ebay and looks great, but I only wanted the autodim and nothing else really mattered. I was thinking I could keep the auto wiper part attached at the window and just remove the mirror and attach to the other one.
