Yes it was at least until a few weeks ago, after my report many people on different forums replied they have purchased it and either installed them selves or made an appointment and had a Tesla technician install for them, it takes 2-3min to install. A Tesla Technician is still required to reconfigure the vehicle, perhaps they are now refusing to do this due to the logistical nightmare if thousands of customer inundate them with service calls to reconfigure vehicle system firmware. This is the Data-enabled USB Hub part number 1755200-00-B. If you look in the parts catalogue this isnt/wasnt a restricted part meaning public could purchase it. Many parts are marked restricted hence they will not sell to public and only Tesla Authorised service centers may purchase. It only costs 30 pounds. Hopefully the Tesla Dictator hasn't changed the classification of this part to restricted
