1. updated through after-sales 4s shop;

2. Download the navigation upgrade installation package on the network or official website to update;

3. Download the electronic map that matches the navigation from the Internet and update it.

The role of navigation:

1. Set up public places. For home, work and common locations, you can set them in the map in advance, or even directly control the map by voice, and plan to go home or go to work with one click. The first three * * * similarities will be actively displayed, so adding three * * * similarities at home and at work can basically quickly navigate to places where most people often go.

2. Make rational use of road conditions. In addition to helping us avoid traffic jams, road conditions also play a very important role in improving driving safety, especially when driving at high speed. Remind the navigation ahead of the red traffic jam Always pay attention to the rear when driving. Because when there is a traffic jam in front of expressway, the speed will be slower and slower. If there is a big truck in the rear, be sure to pay attention to whether the big truck will stop and choose the right lane according to the road conditions.

3. Map navigation Besides two-dimensional navigation, there are some satellite maps of urban areas. Like Baidu live map, if you want to go to a strange place, want to know where you can park and which exit you can take, you can open the satellite map and know in advance.

4. Use simulated navigation to understand the road conditions. Although navigation can guide the way, sometimes it is easy to miss the exit when you go to a complicated overpass or a complicated high-speed overpass. Therefore, after passing through the complicated overpass section, it is recommended to use simulated navigation to look at the road conditions in advance to avoid going the wrong way when you get to the overpass.
