Translation of deviation in German

Anyway you let me know...the rest of the days I will be busy with the course. I am Italian but I live in Wien, Austria. I have not heard back from you since I sent you a message. Do you still want to chat my friend?
On the first day in Hanoi, we wanted to explore the town. It was the former capital of the North and today it is the capital of the entire country. There are tons of monuments and governmental buildings.
We first took a regular bus to the border, which was basically just an empty building. There we switched to Jeeps, as the terrain was rocky. In our group there were 4 American girls and us.
