yes, not sure of the macan compatibility, it says :
1 The new Porsche Track Precision app is available for all Boxster, Cayman and 911 models, as well as for all GT cars with model improvements from CW45/16. The Porsche Communication Management (PCM) version 4.0, as well as the equipment options Connect Plus and Sport Chrono Package are required to use the app.
so pcm 4.0 : check, chrono:check, connect plus:check .. just need to see if a GTS is classified as a GT .. (or just go out the the car and see if it connects)
however, there are plenty on this forum with compatible cars, so a little heads up for those that can.
just been out to the car to test, and it all connects fine, but i am not sure if it will work yet, as no track near by (and dont have time to "make my own" that seems to be an option)
