2004 Z4 Homelink/Mirror Remote?

I have searched the threads but could not find the answer. (Sorry).
I just purchased a 2004 Z4 and the mirror has the 3 button on the bottom of it. Does that mean it is compatible with my garage door opener and can be programmed? Or could the buttons be dummy buttons that dont really work? There is nothing in the owners manual about it at all!

Allen, Texas

Is there a LED light that comes on when you press the button? If not, it may not be getting power.

Homelink programming

Homelink programming is pretty standard. Depending on how things are set there are two phases to it. You may only need to perform the first phase, just gotta try phase one and see. But typically with new rolling code GDO's you need to do both. Its not all that hard.

LEGAL Disclaimer that I claim no inherent responsiblilty for the humor or humorlessness of - If your garage door falls on you or something generally bad happens, you soley choose to exercise your free will (my psychic powers have faded with age, and most people have enough heavy metal in their diet to deflect my abilities anyway) and followed this procedure. While I will feel bad, you choose to perform these directions, and I am not liable for your decisions and your general ability to stand on an elevated platform and push two buttons at the same time. By all means though, please make sure there is nothing and no one under the garage door, and of dont do stupid things that will later show up in a Jack A## movie. (Sorry all you ambulance chasers, not today). In any event....
Phase 1:
1. Turn your vehicles ignition to the "Run" (or "accessory") position.
2. Hold the handheld transmitter that already opens and closes the garage door 1 - 3 inches away from the HomeLink buttons in you vehicle (do not block your view of the HomeLink indicator light)
3. Simultaneously press the transmitter button and the HomeLink button you wish to program (you may need two hands). Hold both buttons pressed until the indicator light changes from a slow flash to a rapid flash.
4. Rapid flashing indicates successful programming - Release both buttons previously pressed.
5. Press and hold the newly programmed HomeLink button.
6. If its indicator light is solid (not flashing) your garage door should now activate and you are complete. There is no need for Phase 2
If the indicator light flashes for 2 seconds before turning solid (not flashing) your garage door opener is rolling code technology and you must continue Phase 2 of these instructions.
Phase 2:
1. Locate the "Learn" (or "Smart") Button on the motor-head unit of your garage door opener.(Yep, thats the big motor thing on the ceiling). This button is normally located on the back side, near the hanging wire antenna. Consult your manual for exact location.
2. Fully press and quickly release the "Learn" Button (holding this button pressed for too long will erase all existing transmitters and keypads and they will need to be reprogrammed into the unit)
3. Within 30 seconds of pressing the "Learn" Button, return to the vehicle. Press the desired HomeLink button for 2 second, then release. Repeat this one step up to 3 times.
4. Your Garage door opener should now activate with a single press of the programmed HomeLink button.

If you have a brand new GDO in your house it gets simpler, nothing is programmed. your users manual should give you much abreiviated instructions which are also pretty much what you would use if you wipe out all the codes accidentally.

Have fun

Let me add that if you have an older garage door opener it may not be compatible. That was my situation. Called the manufacturer and they had a "module" which could be installed. It then worked.
