You can get the auto-dimming mirror with the backup camera, or with the compass, or with the compass and Home-Link.
I bought the latter and had it installed by a detail shop that was doing some other work for me....but it didn't seem like a difficult install.
I kept the original mirror and may swap it back when I trade in the 9 for something else.....then I'll sell the better mirror on eBay.
Found a used one on line from a 5. just bought the wire harness from the dealer and installed it myself. all in under 100.
It had the homelink, autodim and compass. It was worth it just for the homelink.
I installed mine myself. Parts were bought from mazdaparts.org. (mirror + adapter kit for rainsensor)
The tricky parts are
- removal of old mirror using a special-made tool (you need to DIY) with steel wires
- removal of A-Pillar trim (read instructions carefully)
Other than those, piece of cake to DIY.
I have the Autodim+HomeLink+Compass. Since I have the GPS, the compass is useless to me.
Somehow, one cannot get a unit with
HomeLink+Backview+Autodim. I think the last two work against each other.
Those units are made by Gentax (or Gentex). They are universal saved the adapter kits, which you need to buy
from automakers to fit specific model you own.
4wardmotion-That is a really good price. No tax or shipping either.
I had contacted Sita Goss at Open Road Mazda in Morristown, NJ 973-796-1300. She quoted me $396 for the rain sensing compass, homelink, dimming mirror and installation. I feel that is reasonable and I am willing to pay a little more to have the Mazda specialist install it with a warranty. My wife's truck is too nice to risk it. A might have some new speakers put in it too. I am not very happy with the Bose "upgraded" speakers.
On a side note Sita really knows her stuff and is very personable. She also has a CX-9.
