I found a work around for Homelink by putting the vehicle in park after backing out of the garage. Close the camera's front view and only then activate the garage door to close. After the garage door fully closes, I can put the vehicle in reverse, back out into the street and drive away. As for the sensor placed higher, we placed the MyQ sensor at the top of the garage door. The results were the same. The door reversed and reopened if I put the vehicle in reverse prior to fully closing. Haven't really experienced issues opening the garage door when entering the driveway. The vehicle appears to require a straight shot toward the garage door in order to initiate opening. Hey, it works, just not like it was imagined. It only reinforces a favorite comment, "How is the technology working for you?”
