What are the reasons why Mercedes CarPlay cannot start?

[Nicole]

There are several main reasons why Mercedes CarPlay cannot start: The vehicle does not have CarPlay: Use the knob to click the phone menu on the screen twice, or directly press the TEL button on the panel twice. The phone function interface will appear on the screen. If there are only three options: phone, internet, and phone information, it means the current vehicle does not have CarPlay. Incorrect connection mode of the phone: Check the connection mode of the phone. When connecting the phone to devices like a computer or car, the phone's developer mode is usually activated. The developer mode generally has options such as charge only, file transfer, and USB debugging. Pull down the notification bar or enter the settings to find the developer mode and check if the phone is in the "charge only" state.
