Request: Homelink mirror install

GonGo

That did it!.

Now i realize the homelink function powers up from the battery and the auto-dim+Compass use the ignition power...

Thanks for the help!.

I didnt get the Homelink programming instructions on my kit; only compass and autodim information was included.

Here are the programming steps taken from HomeLink

1. For first time training, press and hold the two outer HomeLink
   buttons, releasing only when the HomeLink indicator light begins to
   flash after 20 seconds. (Do not perform this step when training the
   additional HomeLink buttons.)
2. Turn your vehicle’s ignition switch to the second (or "accessory") position.
3. Position the gate operator handheld transmitter 1 to 3 inches away
   from the HomeLink surface (located on your visor, overhead console, or
   mirror), keeping the HomeLink indicator light in view.
4. Using both hands, simultaneously press and hold both the desired
   HomeLink button and the gate operator handheld transmitter button.
   Continue to press and hold the HomeLink button while you press and
   re-press ("cycle") your handheld transmitter every two seconds until
   the frequency signal has been learned.
   
   Note: It is advised to unplug the device during the "cycling" process
   to prevent possible motor burn-up.
5. The HomeLink indicator light will flash, first slowly and then
   rapidly. When the indicator light flashes rapidly, both buttons may be
   released. (The rapid flashing light indicates successful programming
   of the new frequency signal.)
6. Now press and hold the programmed HomeLink button and observe the
   indicator light. If the indicator light is solid/continuous,
   programming is complete. If the indicator light blinks rapidly for 2
   seconds and then turns a solid/continuous light, proceed with the
   following rolling code programming instructions.
7. Perform these steps only if your gate does not operate after
   completing Step 6.
   
   At the garage door opener receiver (motorhead unit) in the garage,
   locate the “learn” or “smart” button (usually near where the hanging
   antenna wire is attached to the unit). If there is difficulty
   locating the training button, reference the garage door opener’s
   manual or contact us.
8. Press and release the “learn” or “smart” button (the name and color of
   the button may vary by manufacturer). NOTE: Once the button is
   pressed, there are 30 seconds in which to initiate the next step.
9. Return to the vehicle and firmly press and hold the programmed
   HomeLink button for two seconds and release. Repeat the
   “press/hold/release” sequence up to 3 times to complete the training
   process.

To operate your entry gate using your HomeLink system, simply press
the programmed HomeLink button. Activation will now occur. For
convenience, the gate operator handheld transmitter may also be used
at any time.
