I can’t find any information on what this button operates, how to use it. Any thoughts? Thanks
it is not a button,
it is an indicator light for the qi (pronounced chee) wireless charging pad.
The storage area there can be used to charge phones that support the Qi Standard
Samsung Galaxy S5 and above, iPhone 8 and above
It only illuminates when a phone is charging.
This is only in the Elite trim in the US.
Also looks like your not using either Android Auto or Apple Car Play.
Plug you usb cable in direct and take advantage!
