Tip for Roadster owners who did not opt for the $3000 electronics package: I did not opt for the electronics package - I planned to add my own radio. While I was getting my radio replaced, I planned to add a built-in garage door opener. The literature around the electronics package all mention the Homelink garage door opener as part of it - I assumed that meant not getting the electronics package meant not getting the garage door opener. However: (at least in my car) it turns out that the Homelink garage door opener is in fact installed. Navigate to it from the touch screen and train it using a separate opener - it apparently lives underneath the left side of the dashboard. There is no need to add a third party one just because you didn't get the electronics package.
