I have been using navigation for a hazardous material truck for 2 years. I have 3 questions below. if anyone knows the answer, please give me feedback or where can I get an answer to my questions.
1. Question about tunel ADR .Why does the navigation allow me to drive through the ADR tunnel on the A7 IN HAMBURG? the map is always updated if there is a necessity message.
2. the reverse is the case on the border between France and Spain via the A9 / AP7 motorway. On this road, navigation forbids me from going and shows a very long detour.
3. next question why navigation allows me to drive over the bridge on the A1 motorway over the river Rhine in Kolonia in German. there is a tonnage limit.
