What does 'No offline data for the starting city' mean?

[AveryRose]

No offline data for the starting city means the navigation data needs to be updated, as there is no data for your current location. Methods to update starting point data: If the vehicle's infotainment system has internet connectivity, you can directly update the system through the in-car navigation interface to upgrade the vehicle's navigation system. Alternatively, you can remove the navigation SD card, download the update data from the official navigation system website, and perform the update. Functions of starting point data: It not only allows you to view offline maps but also enables offline location searches, route queries, and navigation without consuming any mobile data. Simply download the map in advance. It's an essential tool for travel. Mobile navigation apps can also download offline data packages.

I often encounter this prompt, 'No offline data for the starting city.' Simply put, it means the offline map for your departure location hasn't been fully downloaded. Navigation apps usually require pre-cached maps for offline use, and this prompt indicates it can't find the data package for your current location. Once during a self-drive trip to Western Sichuan, I faced this situation when my phone suddenly lost signal in the mountains, causing the navigation to stop working entirely. The solution is simple: Before departure, connect to WiFi, open the offline maps feature in your map app, and manually download the complete regional package for your city. If you see this prompt while already on the road, quickly find a place with internet access to download the missing data—it's fast and won't disrupt your trip. I also keep the auto-update option enabled to ensure my maps are always up-to-date during business trips or vacations.

After driving for over a decade, nothing annoys me more than navigation failing mid-journey. This notification indicates missing offline maps for the vehicle's current location. To save data and function in areas with poor signals, navigation apps require pre-downloaded offline map packages. My routine before long trips is to open the mobile map app and verify offline data availability for the origin, destination, and cities along the route. If this alert pops up, it means either I forgot to download the maps or the outdated version was automatically cleared. The remedy is immediately accessing the app's offline maps section to download local data - preferably using free WiFi, as even small city maps can consume hundreds of megabytes. While at it, enable auto-updates for frequently visited cities' offline packages to avoid constant maintenance.

Explanation of 'No offline data for the starting city' means the navigation software lacks an offline map backup for the current city. Offline data allows you to navigate normally in tunnels or remote areas without signal. The solution involves three steps: Open the map app, enter the offline maps menu, search and download the complete package for the current city. After downloading, remember to switch to offline mode to test the functionality. It's recommended to regularly clean up old data to free up space, keeping only the most recently needed maps for efficiency. I rely on this trick to save data while traveling for business.
