2016 Elantra GT - Gentex (gntx-1070) mirror HomeLink not working
I upgraded my mirror which only has the BlueLink and SOS buttons with another mirror that I purchased from eBay (Gentex GNTX-1070). The wiring harness/connector from my car connects directly to this mirror's connector and the power lights comes on.
The auto dimming along with the compass works, but the HomeLink unit does not work. The instructions says that when pressing any of the HomeLink buttons the light should flash red because none of the buttons are programmed and that I need to press both the outer buttons together for about 20 seconds then the green light should flash indicating that it's ready to be programmed, but nothing happens.
The new mirror also comes with a a wiring harness which one end connects to my car's wire harness and the other end connects to the mirror and also two wires that connects to the constant 12v power. I then went through this wiring method and again, everything seemed to be powered up but the HomeLink buttons don't seemed to do anything.
I am thinking that either there is still a wiring issue, or that this new mirror is defected. Anyone with experience with this particular mirror would be kind enough to respond with some advise is very much appreciated!
