Issue: Route guidance does not appear on the glasses during navigation

Solution:
1. Text prompts appear on the glasses at key points along the route.
2. By default, the glasses display a direction indicator, mini map, and route progress. Double-click to switch to the full route view, or single-click to switch to simplified mode.
3. To view the entire route, double-click the glasses button to open the full route view.
4. Make sure Navigation is still running in the MemoMind App. You can check the navigation status in the app.
