Tesla S/X console support for phone charging has been a challenge, because the supplied slides don't work with any of the phones we've had (and we typically get new phones each year). There is such a wide range of phone width and depth, plus different width and depth of phone cases, that trying to get the slides on either side of the phone plus the USB plug at the bottom of that area all to line up for easy charging; has been a major challenge.
Wireless charging is a much better solution - and if all it takes is to replace the rotating cover that has the phone dock with a new version that includes a wireless charger, with slides that can basically accommodate any phone in any case (that supports wireless charging) - this is a significant improvement.
And if Tesla offers this as an upgrade for current S/X owners, we'll order one each for our 2017 S and 2018 X the day it's available.
