You want to use a navigation device mounted on your motorcycle. What should you observe?

Your selection of all three options is correct because they align with the guidelines set forth in German traffic regulations for using navigation devices while riding a motorcycle.

1. Entering the destination while stationary is crucial for safety. The StVO (Road Traffic Regulations) emphasizes that operating any device while in motion can distract the driver and compromise road safety.

2. Avoiding the operation of navigation devices while driving helps maintain focus on the road. Distractions can lead to accidents, which is why this precaution is necessary.

3. Using a voice output function integrated into a headset allows for hands-free operation, minimizing distractions and enabling you to keep your eyes on the road, thus adhering to the need for safe driving practices.

Together, these three points ensure the safe use of navigation devices, adhering to the principles of road safety mandated by German traffic laws.
