What's the difference between car navigation and mobile navigation?

The difference between car navigation and mobile navigation is that car navigation is a kind of special equipment, which is simpler to operate and has stronger special functions of driving navigation, but its comprehensive functions are far less than those of mobile navigation. At present, mobile navigation can fully meet the needs of driving, and its comprehensive functions are more powerful, far exceeding car navigation. Mobile navigation, for example, can use the Internet to provide road facts, more detailed geographical information, which can be updated at any time more conveniently, provide navigation functions such as riding and walking besides driving, and provide information such as city buses, subways, long-distance buses and even railways with the help of maps.

The following details:

1, mobile navigation: Start the map software of mobile navigation and the map will be displayed. The picture is concise and three-dimensional, highlighting roads, streets and various information points, which looks like a lot of information. It can be used by pedestrians as a guide for buses, subways, taxis and other means of transportation, and it can be said that it has a wide range of uses. At the same time, it also absorbs dynamic traffic information to avoid congestion and accident sections. Mobile phones basically use A-GPS positioning mode, and navigation needs traffic.

The biggest advantage of using mobile navigation for car navigation is its convenience. The mobile phone is at hand, so you can use it when you pick it up. China's geographic information data collection is a secondary qualification, and Gaode has a first-class surveying and mapping qualification. Baidu needs to borrow a third party, and the collected data needs to be submitted to the Bureau of Surveying and Mapping for review, not updated to users, so the progress of car navigation update is similar, the difference is which one will collect data more attentively and collect data more comprehensively.

2, car navigation From the hardware point of view, the current mainstream is the perfect integration of car-specific DVD navigation, embedded host, and central control, generally 7 inches, the largest display screen is 10.2 inch, which is much more intuitive than the display screen of a mobile phone of about 5 inches.

1) supports real-life navigation in vehicle environment (hardware support is required). Combined with the camera to collect the real scene of the road outside the car in real time, the GPS signal is used to locate the position of the car in real time, and the direction indicator light is directly superimposed on the real scene in real time for very intuitive picture navigation.

2) Search along the road. Support to search common POI types within 500m on both sides of the planned route, and clearly show whether POI points are on the left or right side of the planned route. A place to eat, stay, refuel and park during the trip. Most navigation has this function.

3) Lane information indication. Inform the number of lanes ahead and turn information in advance, guide the owner to choose lane change according to the planned route, and avoid the trouble of violating regulations or detours.

4) Electronic eye data is upgraded separately. This is a very economical and practical driving function.
