Just for clarification, here's what I did:
Pushed the program button on the opener unit
Pressed and held the homelink transmitter button
Then, nothing happens. The led on the opener is supposed to flash when it "learns" the remote code. The same thing on all three doors.
FWIW, the two outside buttons on the Homelink pad flash when pressed, the middle button stay solidly lit.
I want to make sure I can get it to work before I install it in the vehicle (cutting the head liner & such).
P.S. thanks for the responses so far.
