Hello,

I had a Gentex Auto-dimming Mirror installed in my wife's CX-9. This was a Christmas gift. The mirror was installed at the dealership Friday.
The auto-dimming feature and compass work fine. I am having no luck with the Homelink. I followed the basic instructions (hold outer Homelink buttons down together for 20 seconds). Nothing seems to work. The LED light remains a steady green no matter what buttons I push. I never get a blinking light or a red light. I called Homelink and had them walk me through programming. They determined there was a problem b/c the green light remained steady. I have programmed several Homelink systems in my life and this one is just not responding--this is not a syncing problem--it never gets to that point.
Has anyone had this problem? Right now my wife has a really expensive compass in her car--not much of a Christmas gift. I am going back to the dealer but what to go armed with some info:
1) Is this a defective mirror?
2) Is this a wiring issue?
I appreciate any info that you can provide.

Thanks,
Ed

 

If the light doesn't turn red when you press the homelink button it's not getting 12V on the yellow wire.

 

Hey,

I am about to order a rear view mirror for My Mazda 3.
There are 2 parts available:
0000-8C-Z27 = mirror with compass, homelink, with rain sensing wipers
and
0000-8C-Z02 = Mirror with compass, homelink, without rain sensing wipers.
I dont get with and without refer to the car or the part?
If my car already has rain sensing wipers, should I choose mirror with rain sensing wipers (its connections matches with my cars sensors) or without rain sensing wipers (no need to buy the sensor since my car already has it)?

could you please help me?
