We just purchased a 2019 CX-5 Signature and just realized after a night time drive the car does not have auto dimming side view mirrors. What the heck? With all the safety features in their top line, why not have auto dimming side view mirrors. Makes you question who is thinking their product lines. I know they make them because my husband has them on his 2019 Mazda MX-5. Any hoo...............has anyone swapped out the side view mirrors for the blue tinted hydrophilic exterior mirrors, Mazda part KC9E-V3-660 (for blind spot monitoring and heated mirrors)? If so, your thoughts - good or bad?
