Occasionally, when vehicle positioning is inaccurate, the head unit automatically replans the route, while the phone route requires re-sending navigation to the head unit. Is there any solution?
The in-vehicle map navigation prioritizes the user's preferred route. If the positioning signal becomes extremely weak causing disconnection, upon regaining signal, it will replan the optimal route based on the vehicle's new position. This is classic map navigation logic. After the phone navigation route is cast to the head unit, we assume the driver will prioritize referring to the in-vehicle navigation route.
If you strictly require the in-vehicle and mobile phone navigation routes to be consistent, you can resolve this by adding waypoints on the phone or head unit. At that time, the head unit will navigate sequentially to each waypoint according to the push order until reaching the destination.
Additionally, navigation traffic conditions are updated in real-time based on direction and road conditions, which may result in suggestions for more efficient routes. In such cases, the system will prioritize adopting the new route for navigation. During navigation, multiple alternative routes are also provided in real-time, allowing you to switch as needed.
