So we bought my wife's '15 Rav4 Limited in November last year and didn't even realize until we got home that it didn't have Homelink in the mirror. Her 2008 Prius had it and my new '16 Tundra has it. Very surprising since her's is the limited model. Anyway, I bought her the Gentex mirror on Amazon for Christmas and finally got around to trying to install it today. Removing the old mirror (w/auto dimming) was very easy and the wire harness for the new mirror is the same plug. Unfortunately the car only supplies power to the auto dim feature to the new mirror when the car is on, and the Homelink doesn't receive power at all whether the car is on or off. Very disappointing that the existing harness doesn't have power for both since it's an available option from Toyota. In looking at the new mirror's plug, there are four wires. I assume two are for switched 12v when the car's on to power the auto dimming feature and compass and the other two wires are for constant 12v power for the Homelink. Instead of ripping apart the A pillar and roof, I think I might just jump the two wires over to power the Homelink so at least when the car's on both will work. I don't think it matters too much that the Homelink won't work unless the car's on and is more of a security feature since you can't open the car garage unless you have the car keys. My only concern with that is if the Homelink will save the door opener code if the mirror doesn't receive constant 12v and if there's a battery inside the mirror.
Anyone have any experience with this?
