What should you note when using your navigation system?

You answered correctly because both points 1 and 2 are important rules for using a navigation system in Germany. First, you must consider the vehicle dimensions on the proposed route to avoid situations where your vehicle might be too large for certain roads, like narrow streets or low bridges. This ensures safety and compliance with traffic laws. Second, mounted navigation devices must not obstruct your forward view while driving. This rule is in place to maintain clear visibility and prevent distractions or hazards. Point 3 is incorrect because the navigation system does not automatically account for mandatory driving and rest periods; it is the driver's responsibility to manage these according to regulations. Remembering these points helps you use navigation systems safely and legally.
