Owners of crossovers Changan CS55 Plus are often faced with the need to integrate their smartphone into the on-board multimedia system to access navigation, music and calls. A modern car is equipped with an advanced operating system that supports protocols Android Auto both in wired and wireless format. However, the pairing process has its own nuances, depending on the firmware version of the head unit and the model of your phone. Correct setup ensures driving safety and comfort, allowing you to control phone functions by voice or via the car's touch screen.
Before starting the procedure, it is important to make sure that your device meets the technical requirements. In most cases, for stable operation you need a smartphone based on Android version 8.0 or higher, although older models are also suitable for basic Bluetooth functions. The key point is to choose a high-quality USB cable, since cheap analogues often only support charging, but not data transfer. It is also worth checking whether the car software is updated to the latest available version to eliminate compatibility errors.
Next we will look at a detailed algorithm of actions that will help you set up the connection without unnecessary difficulties. We will look at both standard connection methods and ways to solve common problems when the system does not see the device or the connection is constantly interrupted.

Use the original cable that came with your smartphone or a certified analogue labeled "Data Sync". The cables that come with cheap power banks are often not suitable for data transfer.
Setting up a Bluetooth connection for basic functions
If your goal is to make hands-free calls and stream music through a media player, it is enough to set up a standard Bluetooth pairing. This method is universal and works even on smartphones that do not support full-fledged Android Auto. The process begins by activating device visibility in the phone settings.
On the central display of the car, go to the communication settings menu. The interface may differ slightly depending on the model year, but the logic remains the same. You need to find the section responsible for managing external devices and start searching for new gadgets.

In some cases, the system requires manual activation of developer mode or special permission in the USB settings. Check the default connection settings in your phone settings. They should be set to "File Transfer" or "Android Auto" mode, and not "Charging Only".
To check if it works correctly, try starting the navigation. If the map loads quickly and voice prompts are heard through the car speakers, then the data transmission channel is working properly. If errors occur, try reconnecting the cable or rebooting the car's head unit.
☑️ Diagnostics of a wired connection
Wireless Android Auto connection
Modern configurations Changan CS55 Plus support Wireless Android Auto technology, which eliminates the need to use cables. However, this method is more demanding on system resources and the quality of wireless modules. To work, it is necessary that both the phone and the car support this standard.
Activation of the wireless mode usually occurs through the phone's projection settings menu. Make sure that Wi-Fi and Bluetooth modules are turned on on your smartphone, as they work in tandem: Bluetooth is responsible for the initial handshake, and Wi-Fi Direct is responsible for transferring heavy traffic.
