Busted the passenger side mirror on my 2017 CX-5 Touring. Though busted up the BSM still worked. The dealer quoted me $550 plus labor. I bought a replacement for $130 and ordered just the matching color cover from the dealer for $54. Went to a body shop who had done some work for me and they charged me $150 to install it. BSM didn't work after install. Part #MA1321198 (which I received) matches the Mazda #KB8C69121A. In confirming the part number the parts guy at the dealership said the BSM had to be "recalibrated". I don't see any other references to recalibration. If the mirror is right for the trim shouldn't it be plug and play?
