"homelink"
 

So there's no homelink on the 86 , and i like the frameless mirror anyway. so im thinking... is there a product that opens the door when you get into a certain proximity to your house and closes it when you get out of that proximity?

It would be great if you could open the door with our phones, but according to a quick google search it seems quite complicated (or not possible , depending on the type of garage opener you have)

Not sure about Australia but in the US you can get Homelink on the BRZ, and by extension it should work on the 86. Subaru part numbers are:

H501SCA100 (mirror)
H501SSA040 (Adapter)

Comes straight out of the official Subaru accessories catalog.

I've not used it, but I have friends that that have "Flash2Pass" and love it. I'm probably going to go that route because it works on any vehicle, including motorcycles.
