Sure, glad to help.
Homelink is a licensed, proprietary wireless system used to operate many garage doors and security gates ... including our own. Details here: https://homelink.com/
It's been installed in MANY cars - usually as a trim option - for years; including our model-year 2006 VW. (where it's built-in to the driver's sun visor)
Note that besides convenience, "built-in" provides a certain measure of security as - unlike the "clip-on clickers" - your garage door can't be opened from your car parked in the driveway w/o your vehicle's key.
Although our 2021 AWD ID.4 included EVERY possible "orderable" option ... the built-in capability to open garage doors and gates was NOT included.
We'll not speculate as to how or why VW arrived at this design decision.
However, on ID.4, this capability IS available and integrated into the "replacement" rear-view mirror; which must be purchased and installed separately. (We were provided a $320 "parts only" quote at the dealer's parts counter)
As to "HOW" we did it ... we simply asked the Sales Manager politely; pointing-out the significant business we've brought the dealership's service department over the last decade w/ our 2x "older" VWs (2000 & 2006); which we STILL own, operate, and maintain.
Congrats on getting the car.
