installed an autodimming rear view mirror with compass

[MaxPower]

Just installed a Gentex auto-dimming rear view mirror with compass that I pulled from a crashed Mazda 6 ($20, but minus $11 for selling the OEM mirror). After figuring out how much extending the mirror's wiring harness would cost, I purchased the Mazda installation kit (part number 0000-8C-B11) from onlinemazdaparts.com for $24 + $8 shipping. I followed the Protege-specific installation instructions I found on a Miata site, and installation took about 1 hour. This particular harness is an older design and does not have a wire to plug into the reverse lights for the mirror to stop dimming on reverse.

The compass is useful, though, if I could choose again I would put the money toward a performance mod rather than a navigational one.

mine doesn't have reverse wire either but I have had no trouble at all reversing at night.

The reverse wire is designed so that when you put the car in reverse, it'll temporary disable the dimming. Don't really need that option tho tbh

I recently did the same. Found a Homelink mirror from a Mazda6. Cost of mirror, and few quick connectors, and different size screw for the mount was <$20. Love it.
