The image displayed by the product is too small and is not shown in full screen. How can this be solved?

1. Confirm whether the same situation occurs when using wired CarPlay; if the original head unit's wired CarPlay cannot display in full screen, then our product also cannot display in full screen

2. Connect to the product's WiFi, enter the password 88888888, open the phone browser and enter 192.168.1.101 to access the backend management page, upgrade the product to the latest version and then test
