Does vehicle navigation require traffic? Do you need money?
Not all free upgrades, when the money
No traffic, look at what brand of navigation you use, some navigation can update their own, do not have money, some navigation to go, they update the official website for money
Vehicle navigation system stored in the national map, electricity can be used, no need to flow, but the inside of the navigation map data is dead, the majority is updated once a year, not update will be lost (some road a year ago may now change to go somewhere else, now the house is displayed on the map, and here the road, which is very dangerous), so that the map to update, update the map some for a fee
First, any car navigator is directly connected with the satellite, without the network, so it does not need traffic.Two, car GPS has two kinds, one is the navigation, navigation is one way to receive signals with good software has been downloaded in the instrument map is displayed, because have downloaded a good map so not networking, so as not to need to flow.One is GPS monitoring, the Y is two-way, not only receive, but also automatically send location information to the background software, to use the network, so you need traffic card support.
