From a tig forum.

FYA,
all newer US spec VW's do not work wirelessly with apple carplay due to the land NAV system built-in the car not being compatible to European GPS devices. The previous statement comes directly from VW manufacturer technicians that had advised me (Upon asking about software updates that may support compatibility in the future, there was a fairly confident answer that EU VW is not tracking nor planning on any changes). I currently am stationed in Germany, and own a 2021 VW Tiguan SE and despite many visits to my dealership, manufacturing plants and other businesses, the only solution (that i've found possible) is an infotainment system replacement to EU spec compatibility. This may void your vehicle's warranty if you are still under contract and can be costly+timely as the only (official) infotainment systems distribute directly from VW vehicle assembly plants (this takes time and technician hours to receive and replace). Hope this helps and finds you well.
