Looks like it comes with some wiring components and taps, nothing special.

I have not looked under the headliner on the 2016 with AT package, but I pulled the camera box off. Remove the small piece in the middle it just snaps off. The large plastic camera box has two orange tabs on the Left and Right side. Disengage on both sides and the box slides down along the windshield glass. The camera wire goes up into the headliner.I have a 2016 SE with the Tech Package, with the basic mirror, no autodim or homelink, i would like to add one. Has anyone validated that even with the tech package there isnt a plug to add the homelink mirror under the headliner? Also, how do you remove the black box on the windshield that goes around the mirror mount. (the box conceals the camera for the safety sense)
Don't know if I should post this here.
I have a Gentex Genk5A brand new that I purchased for my Toyota 4Runner about 5 years ago and never got installed. I totally forgot I had it until I saw this post. I still have the 4Runner but not interested on installing the mirror anymore. I believe its the original from Toyota and it should work with any Toyota vehicle. If someone is interested let me know. Make me a good offer and its yours.
Here is the link of the product.

Are you sure about that model number? Looks to me like it comes with Homelink:I had a 50GENK40A installed in my 2013 RAV4 not long after I bought it and realized it didn't come with Homelink.
Now I'm wishing I had ponied up the extra $ for the Compass option.
