E36 rear view & side mirrors

[kennethw]

Hello all,

I'm looking to change my side view mirrors (stock) to E46 M3 ones which electrically fold upwards. Not too worried about mounting it, but more on the wiring. Has anyone done it before? Is it as simple as doing some re-wiring and use my old switch, and add another switch at the top of the gear stick for the fold-up button?

Is the E46 M3 rear view mirror (oval shaped) a straight swap?

Any help would be greatly appreciated.

Thanks
