Abstract

The invention discloses a system and a method for maintaining navigation destination. The system includes a GPS navigation apparatus and a information service platform, wherein, the information service platform is wirelessly connected with the GPS navigation apparatus and provides navigation service for the GPS navigation apparatus, and the information service platform at least includes coordinate information of a plurality of destinations and provides coordinate information of corresponding destination to the GPS navigation apparatus through wireless transmission. When user increases or updates destination, the invention can send demand instruction to the information service platform through the GPS navigation apparatus, and the information service platform sends back information of the destination and automatically updates electronic map of the GPS navigation apparatus.

Description

technical field [0001] The invention relates to a system and method capable of maintaining navigation destination information. Background technique [0002] At present, due to the liberalization and development of civilian GPS technology, GPS technology has been widely used in civilian positioning and navigation. For example, the car navigation equipment uses GPS positioning means to accurately indicate the current location, and display the route and voice navigation according to the road conditions, which greatly facilitates the driver. [0003] At present, in the way of setting the navigation destination of these traditional navigation devices, no matter it is to find the destination from the map, or to find the destination from the built-in scenic spots in the device, and choose to set it as the destination. The way of the destination, no matter which way is more complicated. If the destination does not exist in the built-in information, the user must input the latitude...
