The instrument panel lights up, proving that the engine has been started. 5. Just connect the external device to the USB socket. 6. At this time, the multimedia will play music.

Under normal circumstances, it is impossible to play music only by using the USB interface and connecting it through a data cable. But you can download a Baidu Carlife to achieve this purpose. The specific steps are as follows: 1. First, you need to download and install Baidu Carlife on your mobile phone. 2. Connect the mobile phone to the vehicle through the mobile phone data cable, and open the Carlife application on the mobile phone at the same time. 3. Select USB debugging mode in the settings menu, open developer options and check USB debugging.

In fact, many people like to charge their mobile phones and turn on the navigation while driving. But after a long time, I found that the battery of the mobile phone was becoming less and less durable, which was probably due to damage to the battery of the mobile phone. Because if you charge directly at the car USB interface, such a situation will indeed occur. The USB interface set up in the car is only prepared for normal audio transmission data. The voltage of this interface is only 5V/0.5A. If the mobile phone is left here for a long time, Charging under such substandard current and voltage will cause damage to the mobile phone battery.

The more the phone is charged, the less power it has. It may be that it is being charged through the car’s USB audio transmission interface, and is being used while charging. Although the phone will show that it is charging after it is connected, the current is very small. If you turn on the phone's positioning and navigation at this time, the charging speed will definitely not be able to keep up with the consumption speed, so this situation occurs.
