How to Upgrade the Car's On-Board System?
3 Answers
Car on-board system upgrade methods are: 1. If the on-board system is factory-installed, it can only be upgraded at a 4S store; 2. Download the upgrade from the official website of the navigation brand via the SD card on the navigation host; 3. If using an Android version of the car system, the navigation can be directly upgraded on the operation interface. The on-board system mainly consists of a host, display screen, operation keyboard, remote control, and antenna, achieving digital intelligent navigation for field surveys and travel with accurate maps, geographic information, and clear travel routes. This system uses the instantaneous position of high-speed moving satellites as known initial data and employs the method of spatial distance resection to determine the position of the point to be measured.
Last time I upgraded the car's system was through the mobile app and WiFi, the whole process was quite simple. After starting the vehicle, I opened the central control menu, found the update option in the system settings, and clicked the check for updates button. The system quickly notified me that a new version was available, so I confirmed the download. It processed automatically in the background while I waited in the garage for about 20 minutes with the car parked. After the download completed, the installation began, with the screen displaying a progress bar and a warning not to turn off the engine. Once the installation finished, the car automatically rebooted once, and I noticed a significant improvement in Bluetooth connection speed and smoother music library performance. If I encountered lag or slow downloads, I would switch to a mobile hotspot to strengthen the signal. After completion, I tested the navigation and volume adjustments to ensure everything was working properly. I make it a habit to check for updates monthly to avoid missing new features, which enhances driving convenience.
As a tech enthusiast, I prefer using OTA to upgrade the in-car system because it's wireless, automatic, and hassle-free. After starting the car, navigate to the update page from the infotainment menu to check for new firmware. If available, simply download and install it. Ensure the vehicle is stationary with sufficient battery during the process, and avoid touching the steering wheel while installing. Post-update, the system speed improves noticeably—for instance, voice recognition responds faster. For older models, USB upgrades might be necessary: download the official file to a USB drive, plug it in, and start the upgrade, patiently waiting for completion. After upgrading, always test all functions to avoid lingering bugs. Maintaining it this way is quite fun and can extend the infotainment system's lifespan.
