Programming mirror for garage door opener

[terrylharris]

Just bought a GT. There is only one botton on the mirror. Is it for the garage door. How do I program it?

No, it's for the auto dim.

The Homelink setup has three additional buttons, with white icons on them for each of three openers you can program.

You can not program it. You have to by a new mirror with 3 buttons and install it.
