How to activate BYD Song max traffic?

BYD MAX can activate the traffic volume through the "Traffic Volume" APP in the central control multimedia screen. You can also connect to mobile phone hotspots to use traffic. Maximum vehicle flow activation: 1. Open the "Traffic" APP, and the upgraded system will have this traffic APP. 2. Click the "Activate" button in the upper right corner of the main interface. Since the activation requires networking, if the traffic is not used up during the test, please click the activation button and go directly to the next step. If the traffic during the test period has been used up, clicking the activation button will prompt "no network". At this time, you can click Multimedia Settings-Network-Open WLAN, connect Wi-Fi or mobile phone hotspot, and then click the Activate button. 3. Read the service agreement and confirm it. Check "I have read and agreed to the above agreement", and then click "OK" to continue the next step. 4. In the "Activation" interface, enter the mobile phone number and verification code, and click "Apply for opening". Enter the mobile phone number first, and click Send Verification Code. Fill in the verification code received by the mobile phone in the corresponding position, and click Apply for Opening, and it is completed. 5.
