Haven't seen this one yet: Having an issue with the Homelink portion of my (upgrade) inside rear view mirror homelink/autodim/compass (replacing the auto dim only) purchased second hand but is a plug-and-play unit. The Homelink can only be programmed (or even functional) within minutes of the first ignition cycle. It can be programmed and will open my garage doors during this limited time period, then it reverts to the green light steady (ON indicator) with no response at all. All other functions of the mirror remain operational with the ignition on. Strangely enough, I got it to remain active and work normally over several ignition cycles last evening over an extended period of time when KONA was in close proximity to the openers. I can't seem to identify the circumstances that cause this non-op situation. Any help is greatly appreciated.
