Sorry to revive this zombie thread, but I just want to report back after nearly a year that wireless CarPlay has been grrrreat for me. Not 100%, but 98% of the time it has been flawless. My Pioneer aftermarket unit boots up and connects quickly, usually it’s running before I drive away. Switching between wireless and wired is also seamless.
Honestly, it’s been so good that the factory wired CarPlay in various rentals I have driven this last year are slow and frustrating in comparison. Which makes me wanna ask the forum hive mind:
which car makes/models have Wireless CarPlay standard? I really wouldn’t want to go back to wired-only.
I recommend writing a shortlist of cars that you would like to purchase. Take them for a test drive and try their CarPlay.
Two months ago I purchased a W211 E-Class. The OEM head unit didn't have bluetooth. I used an FM transmitter for a few weeks until I got depressed about the Audio quality. My previous car was a 2019 BMW with H&K.
With nervousness and hesitation, I purchased and fitted a £170 Android head unit which was a fantastic decision. It fits flush and looks OEM. Most importantly, it has a high-end amp and has wired and wireless CarPlay/AndroidAuto.
Connection speeds are the following:
Wired CarPlay: 3 seconds
Wireless: 25 seconds
Similar to your experience wireless is reliable 95% of the time. However, it's a better hog and therefore I tend to use wired for journeys longer than 20min as the battery capacity on my 13 Mini is precious.
