I know this thread is a bit old but I ended up installing the OEM wireless charger and wanted to report back. It works great

Just a note for anyone who wants to order it - I have an iPhone 12 Pro Max and I have to take it out of its case for it to fit. But any phone smaller than that would have no problem at all. It's pretty awesome because now I can have wireless CarPlay and charge my phone at the same time. You can see I've velcro'ed the CarPlay adapter to the ceiling of the compartment.
You do kinda need to remove the glovebox to install it though. If you don't have the cooled AC glovebox, I recommend you order that too and you can do both these mods at the same time.
I used this thread as a guide:
https://forums.ross-tech.com/index.php?threads/12055/. Though, I took some liberties with the wiring because I just wanted to get the center console back together again quickly. Instead of running the +12V wire, ground and BCM wire from the compartment over to the fuse box, I cut all of them much shorter and just spliced +12V and ground into the cigarette lighter wires. I did not even try to attach the one wire to the BCM - it works fine without it and my guess is it's for charging while the ignition is off, which I don't particularly need. Then the two final wires plug into the gray connector in the quad-lock of the infotainment in the glovebox.
I could have made it even easier on myself by ordering one of
these (just the harness). Then there is no need to splice into the existing wires.
For coding, all you need to do is enable bit 0 and bit 5 in byte 15 of module 5F's long coding.
Definitely recommend it!
