Car central control screen upgrade steps are as follows: 1. Download the firmware (remember to select the corresponding version), commonly referred to as the update.zip file. 2. After downloading, connect your phone to the central control screen via a data cable. Once successfully connected, a notification "Connected as a media device" will appear in the phone's pull-down notification bar; at this time, double-click "Computer" on your PC, and "MX4" will appear under "Portable Devices". 3. On your computer, right-click the update.zip file and select "Send to" "MX4". 4. Enter the "Documents" on your phone's desktop, locate the update.zip file, and click on "update.zip". The phone will automatically enter the upgrade interface. 5. The update process will first verify the firmware. After successful verification, it will enter "Upgrading". After a few minutes, it will return to the familiar interface. 6. After entering the system, click the "System Upgrade" icon on the desktop to view the current version number, indicating a successful upgrade.
I've tried upgrading my car's infotainment screen, and it's actually quite simple, especially for software updates. Most new cars support over-the-air updates - just tap the 'System Update' button in the vehicle settings to download the new version. For older vehicles, you'll need to first download the upgrade package from the manufacturer's website to a USB drive using a computer, then plug it into the car's USB port for automatic installation. After upgrading, you can get new features like more accurate navigation maps, additional music apps, and customizable interface themes. But I must remind you: always back up the original system data before upgrading - if something goes wrong and causes screen freezing or system crashes, it could be troublesome. DIY upgrades save money, but don't experiment blindly. First check your vehicle manual or forums for compatibility. Software upgrades are free, but hardware upgrades like replacing with a larger screen can cost thousands - I recommend getting an evaluation from an authorized shop.
Upgrading the car's central control screen, I have experience, but I sincerely advise against doing it yourself. In terms of software, first check if the vehicle system has an automatic update notification, just click confirm; for hardware, you'll need to replace the entire unit, which is costly and prone to issues. Last time I helped a friend upgrade, I installed the wrong model package, and the screen went black, costing a lot to restore at the 4S shop. For upgrades, choosing original manufacturer services is the safest to avoid voiding the warranty; third-party modifications carry greater risks, such as lagging or conflicts with vehicle functions. In the long run, upgrades can enhance the user experience, like a more friendly interface or CarPlay support, but safety comes first—beginners should never DIY, at least have a professional technician check if the circuits are compatible.
Car infotainment screen upgrades are divided into software and hardware. Software upgrades are simple: enter the settings menu to find the update option, click download and install; or download the package from the official website to a USB drive, insert it into the car's system for automatic processing, usually completed in about 30 minutes. Hardware upgrades, such as replacing an outdated screen, require removing the dashboard and connecting new interfaces, but I recommend avoiding it unless necessary, as it costs thousands and may lead to feature loss. Post-upgrade benefits include faster interface response or new apps, but ensure compatibility with your car model to avoid installation errors causing bugs. Overall, most cars receive regular OTA update notifications—just follow the prompts and avoid tampering with core systems unnecessarily.
