Differences between car navigation and mobile navigation
On board navigation is to download the map package into the on-board memory card, and then GPS receives the satellite signal and displays the positioning according to the local memory card.
The advantage is: due to the use of professional GPS positioning chip, the navigation is more accurate. There will be no prohibition of mobile navigation and positioning.
Defect: the update is inconvenient. It needs to download the update manually. Some car manufacturers also charge high update fees. (however, some maps can now be connected to wireless WiFi for active updating)
Mobile navigation can use network positioning and mobile GPS for positioning. There are many positioning methods and convenient operation (the whole process needs network support. If you don't want to use the network to download the offline map package).
Advantages: mobile navigation is updated in real time, with strong comprehensive function, far surpassing vehicle navigation. It can provide road live and detailed geographic information through the Internet. Including traffic jams, where to block, where not to block, at a glance. Where roads are closed, where traffic is restricted in big cities, mobile navigation can also take the initiative to help you avoid.
Defect: power consumption and heating exist in mobile navigation, and people are caught off guard when there is no power suddenly. At the same time, the screen is not large enough, which affects driving safety. Picking up the mobile phone to look at the map will distract the driver. There is no signal positioning effect, which is greatly reduced. Compared with professional vehicle navigation, sometimes the navigation is absolutely accurate.
Conclusion: the best choice is to use vehicle navigation and mobile navigation together. For example, if you use urban navigation, you can use mobile navigation for positioning, and analyze the road conditions in real time to prevent congestion. But if you run long distances, you must use vehicle navigation, because there may be no signal on the high-speed, and the vehicle navigation will more accurately prompt the route selection to prevent you from passing through the high-speed exit (the updated and timely vehicle navigation is very powerful)
