What is the difference between 4G and WiFi versions of car central control screens?
2 Answers
The differences between the WiFi version and 4G version of car central control screens are as follows: 1. Different supported ranges: If it is a WiFi version navigation system, it does not support installing a SIM card. If it is a 4G version navigation system, it can install a SIM card. 2. Different usage methods: The WiFi version navigation system must use a mobile phone to create a hotspot, then turn on the WiFi on the central control screen to connect to the mobile phone hotspot for internet access. The 4G version navigation system can directly install a SIM card for internet access without needing to use a mobile phone to create a hotspot. The 4G version navigation system can also create a hotspot, allowing mobile phones to connect after turning on the WiFi.
I've been researching in-car systems. The 4G version of the central control screen has a built-in SIM card slot, allowing direct internet access and independent operation like a smartphone, without requiring additional devices. It's convenient for updating maps or streaming music anytime in the car. However, the downside is that you may need to purchase a data plan, costing dozens of yuan per month, and coverage can be limited in remote mountainous areas, leading to lag. As for the Wi-Fi version, it can only connect to home routers or mobile hotspots, lacking a built-in network card. While it saves monthly fees for daily use, you must turn on your phone's hotspot when driving out, otherwise the screen becomes half-useless, and offline navigation often makes mistakes. In summary, the 4G version is more reliable with better mobility, suitable for those who frequently travel long distances; the Wi-Fi version saves money but has greater dependency, sufficient for daily commutes—just remember to check your phone's data limit to avoid exceeding it.
