Adding homelink

[uncle ben]

My M3 doesn’t have the homelink rear view mirror. I seen a couple on eBay. Do you think that it’s just a matter of replacing the rear view mirror for one with the garage door opener buttons on it, and then having it coded? Anyone done this before?

I remember doing similar in e46 but Homelink was not in rear view mirror.

I believe all of the Homelink hardware is inside the mirror unit and is plug and play. No VO coding should be needed. I’ve never seen VO code for Homelink.

Just double check if the plug for the mirror is tucked away behind your headliner first. if so, then it should just be a simple plug & play. like a previous poster stated, all hardware is within the mirror itself and doesn't require coding.

And just in case, here’s a good DIY to get to the wiring behind headliner/light assembly

Have you thought about replacing your garage door motor? They now all pretty much come WIFI enabled which allows you to open/close with their app.

Might be easier going this route? just a thought... its only about $200 for a new garage door motor..

Or for even cheaper, add Wifi to your existing door opener:

FYI - you can also program your valve controller to the homelink, which is the only reason I use it. Amazing and no need to fiddle with the stalk, bm3, or some key fob.
