Thanks for the info, so there will be proper micra mirrors out there, do you know how the switch worked, was it in the dash or handbrake area or on the driver mirror?
Would it be reasonably easy to fit them to a gx with manual mirrors? I assume they'll bolt straight on, but then I'll need to wire them in and mount the controls, which I'll assume will be the more difficult part (unless there's already a place for the switch, just blanked out with a plate.)
