My other car (Volvo) has it as standard but I do not see (much) added value and hardly use it. Personally I would not spend money on it.....
Reasons:
Comparing the sound quality of e.g. Spotify through CarPlay with Spotify through the Car’s own built-in app I find the CarPlay version considerably less dynamic.
Navigation through CarPlay is not integrated with the car’s own information (like “navigate to fuel station” when the tank is low etc.) so I prefer the car’s own.
(That system is used anyway to optimize the energy usage from the hybrid battery depending on the route selected and reads the traffic signs and displays these on the screen through HUD).
