Enter the homepage. Go to the settings page and click on 'Check for Updates'. A prompt dialog will appear on the page, click on 'Install Now'. Finally, click on 'Install' and wait for two seconds for the installation to complete.
Last time my car's infotainment system prompted an upgrade, I could do it directly via OTA online update. After parking, I found the settings menu on the car's screen, connected to a stable WiFi network, and the system automatically detected the new version. It's best to keep the vehicle powered on during download, and don't cut the power until the progress bar completes. After the upgrade, the operation felt much smoother, the navigation map updated with many new roads, and the voice assistant even understands dialect commands now. Remember to back up your personal settings to the cloud account before upgrading—my friend lost several saved radio frequencies because they didn't back up. The whole process took about half an hour, much more convenient than visiting the dealership.
The most reliable way is to upgrade using a USB drive yourself. First, visit the brand's official website to download the firmware package for your specific model. Prepare an empty USB drive formatted as FAT32, then copy the extracted upgrade files onto it. Plug the USB into the car's USB port, and select local upgrade in the infotainment system's recovery mode. Remember to keep the engine running throughout the process to avoid battery drain. When I upgraded, I specifically chose a Sunday morning when there were fewer cars on the road to avoid blocking traffic. After the upgrade, remember to recalibrate the tire pressure monitoring system. I also took the opportunity to change the boot animation to a family photo. Ensure at least 5GB of system space is available, and for older infotainment systems, it's best to clear the cache first.
Going directly to the 4S store is the most hassle-free option, so I scheduled a weekend maintenance appointment and also got an upgrade. The technician connected the diagnostic tool to the OBD port, finished everything in half an hour, and even adjusted the sensitivity of the steering wheel buttons for me. The workshop temperature was constant, ensuring the upgrade process wouldn't be affected, and the best part was that any issues were resolved on the spot. After the last upgrade, it automatically unlocked the wireless CarPlay feature, allowing my phone's navigation to be directly projected onto the car's infotainment screen. The store also gave the car a complimentary wash, and while vacuuming the seats, they even cleaned out the cookie crumbs my kid had dropped in the crevices.
