FWIW, we moved into a new house about a year ago. I spent an hour trying to program my Gen1 to the new OH openers but it would never take. I eventually talked to the overhead door installer and he said that since my truck was an '11, that it wouldn't work with a brand new opener. IIRC he said something inside the OH motors changed in '14-'15 and hence the lack of compatibility. He said I'd need something like DWH3 suggested above.
