I have a 2003 330i ZHP with the standard clown nose mirror. I was considering switching to the automatic dimming mirror with compass. Would this require any special mods or would it be a straight swap, plug 'n play kindda thing?
sa may mean standard accessory, it sounds like an accessory number.
it may be for the autodimming feature, and the harness is what you install to get that feature. i want the compass but do you know if they have a compass m3 mirror? i figure if i am going to spend the money to get a compass i might as well upgrade the mirror to the m3 one.
