How to Upgrade the In-Car Navigation System of Volkswagen Lavida?

Enter the navigation interface, click on the menu, then select function settings, and click on 'About Navigation'. Inside, there is a navigation information button. Click on it to view the serial number and version information. The system will prompt whether to upgrade. Select 'Yes', and a dialog box for starting the upgrade will pop up. First, select Amap Navigation, then choose to upgrade. Here is some extended information about car navigation: 1. The built-in GPS antenna in the car navigation system receives data from at least 3 of the 24 GPS satellites orbiting the Earth, thereby determining the car's current location. The navigation host matches the position coordinates determined by the GPS satellite signals with the electronic map data to accurately locate the car on the electronic map. 2. The car navigation system mainly consists of two parts: the navigation host and the navigation display terminal. Based on this, it can achieve various functions such as driving navigation, route recommendations, information queries, and playing AV/TV. The driver only needs to watch the display screen, listen to voice prompts, and operate the remote control to achieve the above functions, making driving effortless and comfortable.
Last time I went to the 4S shop to update the navigation system, they asked me to bring the car key and vehicle identification number. The staff first checked the infotainment system version and said that the old Lavida models with MIB system required SD card updates. The newer models with LCD screens can directly connect to WiFi to check for updates. The safest way is still to have it done at the 4S shop, where they use specialized computers to download map packages and flash the system - the whole process took over two hours and cost around 400 yuan. DIY attempts can easily go wrong; there was a case where an owner downloaded a pirated map package online and ended up crashing the head unit. After the update, remember to ask the technician to calibrate the GPS positioning, otherwise the navigation may drift. With phone mounts being so convenient these days, using CarPlay to mirror Amap is actually more hassle-free.
I upgraded the navigation system of my 2018 Lavida by myself. First, I noted down the last seven digits of the VIN, then accessed the FAW-Volkswagen official website on my computer and found the map update section under owner services. After registering an account and entering the VIN, the system pushed the corresponding map package. The key is to prepare a 64GB USB flash drive formatted in FAT32, download the compressed package, and extract it to the root directory of the USB drive. In the car, turn on the ignition, hold the MENU button for ten seconds to enter engineering mode, and select software update. The entire process must not be interrupted by power loss—I squatted in the car for over forty minutes. After the upgrade, I noticed some stuttering in the voice announcements, which I later resolved by finding a firmware update package on the forum. I recommend cracking the windows a bit for heat dissipation when upgrading in summer.
