Each Homelink button transmits one code. The Genesis has three buttons and so can control three things. For 3 garage doors you need to use one of the Homelink button for each door. Program each button as if it was a remote. Left most button for left garage door, middle button for middle door etc. etc. If helps if you have a helper to push the learn/program buttons on the garage door openers too. I started by driving a distance from the house to program the Homelink buttons so as to not drive the garage door crazy during the Genesis button programming. There's a two step procedure, first program the car with the old remote. Then program the opener with the newly set car's Homelink button. For the first step, remember to hold both the remote and the Genesis Homelink button down for 20 seconds or so until the Homelink's LED flashes slowly and then fast (or is that fast and then slow? Whatever) and then release both the garage door transmitter button and the Genesis button being programmed. Then move on to the next transmitter and button. When all three are programmed, return home and with your helper go through the garage door opener learn cycle for each door. If you have 4 functions you will need to keep one transmitter since the car's Homelink can't control 4 things. Unless you clear the garage door opener's memory, each opener can store more than one remote's codes. So don't mess with other car's transmitters and they should still function as before.
One thing that I wish would be that the Homelink buttons were lighted at night, trying to push the correct one sometimes results in garage door shuffle unless I get lucky and push the right one first. If you have just one door to open then I guess you could program all three to work the one door. I'm not so lucky.
