It is best to go to a 4S shop for after-sales service or to an auto repair shop to upgrade the car navigation system. The following is an introduction to relevant information about car navigation: 1. Common car navigation maps: In China, the most widely used map versions include Kailide, Daodao Tong, CJT, and AutoNavi. Relevant information will be promptly released on the official websites of major map companies. 2. Correct operation methods for car navigation: (1) When using it, you should first close the page and then turn off the machine. It is not allowed to turn off the machine directly without closing the page, which is a violation of operation. (2) Before using the machine for the first three times, it should be charged for about 10 hours to maximize the battery's storage capacity. (3) Start the car first, and then plug in the cigarette lighter power supply. After the navigation ends, unplug the cigarette lighter and plug it in again after the next car start, which is beneficial for protecting the machine's battery.

My experience with upgrading the navigation system in a Mercedes-Benz is that using the car's MBUX system is the most convenient: start the vehicle, enter the main menu, find the navigation settings section, and click the update option—it will automatically detect new versions. Connect to Wi-Fi or a mobile hotspot to download the installation package, wait 10-30 minutes without turning off the engine, and the maps will refresh once completed. Remember to log into your Mercedes Me account to check the subscription status, as some map services require payment; otherwise, certain features may not be available. I've also tried the official website USB method, which works well too: download the files to a USB drive and plug it into the front port, but the download time is longer. The advantage is that the updated routes are more accurate, reducing the chances of getting lost. I recommend upgrading every quarter to ensure safety.

As a long-time Mercedes owner, I recommend the official method for navigation updates: Go to vehicle settings, select Communication & Navigation, find Online Update, connect to stable Wi-Fi, then download and install. Avoid DIY risks to prevent software conflicts. I regularly check the Mercedes Me app for reminders - if updates are available, I proceed immediately. Keep the process quiet and don't drive during installation. After completion, test new features like voice control. Without Wi-Fi, visit a 4S shop where professionals handle it more reliably. Remember to backup settings to avoid reconfiguring preferences. Updating every six months is sufficient to maintain driving peace of mind.

Upgrading Mercedes Navigation Using USB Method: Visit the Mercedes official website, log in with your vehicle's VIN number, download the map data package, extract it to a FAT32 formatted USB drive, insert it into the front USB port, and the system will automatically recognize and install it. Do not disconnect the power during the process, wait for about 30 minutes to complete. Verify the map version to ensure success. This DIY method does not rely on the internet, making it suitable for remote areas, but requires pre-downloading files. After updating, it improves accuracy, reduces detours, and may also add new features. In short, it's simple and reliable. Regular upgrades maintain system smoothness.

When I first got my Mercedes, I was very cautious about updating the navigation: first, I checked the update status in the Mercedes Me app on my phone. After logging into my account, if there was a prompt, I connected the car to Wi-Fi to start the download. During installation, I stayed in the garage to avoid disconnection. After completion, I searched for a new address to test if the function was working correctly. For the first operation, I read the manual or asked a friend for help. It's beneficial to back up frequently visited locations and settings, as it ensures more timely map updates and reduces errors from outdated roads. Now, I check every two months to ensure a smooth and safe journey.
