Some of the choices Chevrolet has made have honestly been a little questionable. The terrible sun visors for example. Ugly and not overly functional. Same for their failure to include Homelink. Why are they trying to wring an extra $12 in profit out of each sale?
Obviously you can keep a garage door opener in the car, there are a number of good places to clip it inside the Bolt.
If for some reason you don't have one laying around you can buy one on eBay and pair it to your opener, or consider purchasing a wifi-enabled garage door adapter. For other reasons I have recently installed a Garadget. It's actually less convenient as an opener then a traditional remote because you must login, but it does give you control of your garage door from anywhere and allow you to get updates when the door opens and closes Etc. While there are a number of these products on the market, 1 particularly interesting thing about this unit is that the software is open source if I understand correctly and someone much smarter than me could probably work out a hack to get it to operate by voice under either iPhone or Android.
Speaking of which, the voice controls on the bolt have been significantly dumbed down to when compared to a first generation volt for example. Again, GM had the software developed, they just chose to dumb down the car. No idea why.
All of that said, still the best car I've ever owned by far. And with that General Motors feels smugly self-assured that they can continue to reap the extra $12 in profit per car.
