Hi All, I noticed that the garage door transmitter only works when the engine is running. With my previous truck I would sit in the truck, open the garage door and then start the truck but it doesn't work that way. Is there any way to tell the homelink system to work when the truck isn't on? I'm sure I'll get used to it eventually but it just seems strange. No biggie though. My silverado had homelink as well and they were always available.
