The reasons why Mercedes-Benz Carlife cannot be enabled are: The data cable and USB interface models do not match, resulting in the inability to connect to Baidu Carlife. You can replace the data cable; The Baidu Carlife in the car's system is incompatible with the mobile phone's system. You can update Carlife; Carlife has not been upgraded or updated. You only need to update the version to reconnect. Because the original data cable has a data transmission function, the data cables purchased later generally do not have this function, which will affect data transmission and cause the inability to connect to Baidu Carlife. You can purchase the original data cable from the official store for connection. In addition, insufficient power supply voltage of the USB connection will also cause the inability to connect, and a USB power supply socket needs to be reinstalled. Some mobile phones cannot connect to Baidu Carlife after updating, or they keep disconnecting after connecting. This is because the Baidu Carlife in the car's system is incompatible with the mobile phone's system. You can restore the mobile phone system or try to update the car's Baidu Carlife. The reason why some models cannot connect is that Baidu Carlife has not been upgraded or updated. You need to download the latest version of Baidu Carlife online for installation, or go to a 4S shop and other places to let professionals help install the latest version.
Last week, I was driving my Mercedes to pick up a friend when I encountered this issue—the CarLife just wouldn’t connect. After fumbling around for a while, I realized the key was in the phone settings: you have to make sure USB debugging mode is enabled first. On the car’s infotainment system, you also need to check whether CarLife is enabled in the multimedia settings, as this feature isn’t turned on by default. Additionally, the data cable is crucial—you must use the original one that supports data transfer, as a regular charging cable won’t recognize the device at all. If it still doesn’t work, try restarting the infotainment system by holding the volume button for 15 seconds to reset it. Finally, don’t forget to update the app. Last month, my phone’s automatic update caused incompatibility issues, and I had to re-download the latest version of CarLife to fix it. I recommend trying all these steps—they’ll solve about 80% of the problems.
I've been repairing Mercedes-Benz infotainment systems for nearly a decade, and CarLife connection failures mainly fall into four categories. Hardware-wise, the most common issues are oxidized USB ports or worn data cables - replacing with an OEM cable solves about 80% of cases. Software problems often occur with outdated system versions, requiring a firmware upgrade at the dealership. For smartphones, two key points: all app permissions must be enabled, especially background permissions; both very new and very old mobile OS versions may cause conflicts. Many overlook network issues - Bluetooth and in-car WiFi frequency band interference can cause disconnections. If all else fails, try resetting the system by selecting 'Restore Factory Settings' in the setup menu.
