Old thread, but thought I would add my experience. Got the wireless charger when I bought the car but didn't have a phone that could use it. Bought a wireless adapter for the phone and it worked fine. New iPhone 12 arrived yesterday and tried it out today. Works as advertised. I found that I have to put in the center of the inside rectangle and wait a few seconds. After a few seconds the green light comes on and stays on. The phone charged just fine.
Do wish that Apple had included the mag safe feature a couple of years ago. If they had maybe Honda would have included it in the charger, then the phone would lock into place in just the right spot.
