I have had my 2018 1LE for a few weeks now. Love the car, but it feels like it's missing an auto dimming inside mirror. Homelink would be a nice addition too, but not necessary.
I found this:

Its a OE auto dimming for 2SS/2LT etc. Is it plug and play? I don't want to lose the Onstar features, and I like the frameless mirror. There are a few options from Gentex for the frameless w/autodim & Homelink, but no Onstar. Any other options I'm missing?
