Has anyone installed the official homelink mirror? I had it installed last week.

Is it supposed to work with the ignition off? I can't open or close the garage unless it's on. My other kia with homelink doesn't require the ignition to be on for it to work. I asked the dealer and they said that's the only way it works, there is no wiring in it for constant because it would just drain my battery. I don't have the actual install instructions only the quick user reference manual.

One other issue, I'm having a hard time getting it to actually open and close my garage. I get it programmed and it will work 1 or 2 times then it just doesn't work. Or I have to hold it for 20 seconds and it will open the garage or it will go into program mode again because I held the button too long.

I just installed the Auto Dimming mirror w/ HL-4 and Compass in my Optima. There were three wires, one for the Hot, one for the On position and a Ground. The Hot should draw very little current, it's there for the HL and keeps the calibration for the Compass. You need to get a hold of the Installation instructions. Since you paid for it, ask who ever installed to give it to you. Something does not seem right with your Auto Dimming Mirror....................

If you had the OEM auto dimming mirror, there isn't a constant 12v line in the original wiring harness, only switched 12V, ground and reverse signal. I wired in a new homelink mirrror with compass for a Rio. Haven't lost programming, need to use with ignition on, and compass holds calibration no problem. You should let the installer know about the problem.

But... there is NO continuous 12 volt in the mirror. It's IMHO due to the fact the Niro has a 12 volt battery the size of a medium size hard cover book. There are only a few places that 12 volts on all the time are available, and you would have to run a wire up to the mirror if you wanted a fully functioning mirror!!
However interesting side note, I just found this URL on a Kia Niro: Charging System / Auxiliary 12V Battery system, ohhh, I want one!

Kia Niro : Auxiliary 12V Battery Repair procedures : Charging System

If I am ever going to properly install 2 way radios in my car, I need a second battery. this will be worth looking into to see if I can figure out to install this in my EX!!

Okay so maybe its installed correctly. I just wish I didn't have to turn the car on in the garage to open the garage but I guess most of the time the niro engine doesn't actually turn on until later. So I'm not gonna fill the garage with carbon monoxide.


And I have reprogramed the mirror about 5 or 6 times so far but tonight it actually opened and closed when I left and came home for the first time without incident.

No switch by the door as you enter your garage to open the door? Bizarre, but if true, will cost only a couple of dollars to put one there. That solves that issue when taking the car out, or closing the door when parking. Or you could clip a remote to your passenger side sunscreen. Both of those seem far preferable to the hassle you are going through.

I think the point of the mirror not working when the car is off is to prevent someone from being able to open your garage door by smashing your window and pressing the button (if you were parked outside the garage). My Telluride, which came with the homelink mirror installed from the factory, didn't work unless the car was in the "on" position. By comparison my Sienna would work as long as the key was within range, which was a much better experience, IMO.

It tends to vary by vehicle manufacturer. Some power the HomeLink at all times, while others kill the power when the car is off, mainly for the reason that @Steve in Denver mentioned.
