Is the navigation designed before going out? What navigation do you use ?

Google Maps is applicable in many countries, but the navigation system may not work well at times. It's better to download the offline map in advance, especially in mountainous areas.

We use Google Maps and the built-in map of Apple phones. We usually book hotels a week in advance. We will not book all the hotels at once. We will stay in Switzerland for a week, Lucerne - Titlis - Interlaken - Jungfraujoch - crossing the Alps to Italy. We booked the hotels in advance in Switzerland, but there are rooms available in other places. The old town of Italy cannot park, so it is more convenient to shop outside. We arrange to visit the scenic spots and play in the afternoon or early evening, and go shopping in the hot noon. We booked the hotel in Lugano, which is on the border between Switzerland and Italy. What I mean is that it is hot in Italy in the afternoon, and you can visit in the afternoon, but you can play all day in Switzerland without shopping. 07 Munich 08 Munich - Schiltach 09 Schiltach - Lucerne 10 Lucerne 11 Lucerne - Grindelwald 12 Grindelwald 13 Grindelwald 14 Grindelwald - Mendrisio 15 Mendrisio - Venice This is our general itinerary.
