I am the best at this problem. From the time I purchased car navigation to the current mobile phone navigation, I have tried it all. I still have the following navigation software on my phone: Google Maps, Kay Rucker, and Baidu Maps.

After setting the starting point and end point, the above software can draw the route on the map. Route planning is about as smart as it gets.

Kaileide is a professional driving navigation software, but it requires more than 1G of memory card space. The software also runs slower. It can be used as a navigation. She has voice prompts (such as "100 meters ahead, turn left onto what road?"). The disadvantage of this software is that it is not very convenient to update.

"Google Maps" downloads map data while viewing the map, which requires Internet traffic. I use the China Mobile Internet service with a monthly subscription of 6 yuan/60MB. Going to an unfamiliar place will use up several MB of data. Since my phone supports WIFI, before going to a strange place, after using WIFI to connect to the Internet, I first browse the map of the place I want to go to at various magnifications. Maps viewed by Google will not be downloaded again if they are not updated. "Baidu Maps" is similar to "Google Maps". The functions are much the same. These two softwares also allow him to plan a bus ride for you (such as how many meters to the east and how many buses to take to reach a certain place and then how many buses to change to reach the destination).

Generally speaking, the main reason for using Kay Rucker when driving alone is because of the voice prompts. Use Valley Map or Baidu Map when you are not driving or out of town. The maps seen by these two are exactly the same as the maps we see online on the computer.

The above software can be downloaded from the "Shouwei Mobile Software Station".
