OGNJ, My garage door opener doesn't work unless the engine is running, not even in "accessory" mode. It's really been a nuisance since all my other vehicles have power constantly and often park and shutdown in the street or driveway, then remember to open the garage door. I may have to see about re-wiring that circuit.I’ve been eyeing BlackVue. Let us know how the install goes. Will you hard wire? That’s how I want to do it. Maybe tap the garage door opener power source?
