It seems there is a lot of inconsistencies throughout the SC's, some have done one of the installs, others will sell you parts no prob but will not install, others will not order parts. Very disorganized, aka Normal Tesla stuff, when it regards to retrofits, upgrades, etc, LOL
FL SC's will order the parts for you, but until they actually release a service option to start to do the install and permanently activate, it's a bit of a waste of time. I installed it on mine but the quirk is that once you reboot the computer, you do get the standard sound and of course no boombox app, but what the others, fail to mention, once the car goes to sleep at night, it stops working and you have to reboot the computer that day once again for it to work. So yeah... wait till you get the official install option.
