　　Road signs

　　The coordinate value of a point stored in GPS memory. When there is a GPS signal, pressing the "MARK" button will mark the current point as a landmark, which has a default name such as "LMK04". You can modify it to a recognizable name (input letters with up and down arrows), and you can also select an icon for it. Road signs are the core of GPS data, which form the basis of the "route" (see 3). Marking landmarks is one of the main functions of GPS, but you can also read the coordinates of a location from a map, input GPS manually or through a computer interface, and become a landmark. A roadmap can be used as a target for GOTO functionality in the future, or a route can be selected as a fulcrum (see 3.). Generally, GPS can record 500 or more road signs.

　　route

　　A route is a set of data stored in GPS memory, including the coordinates of a starting point and an endpoint, as well as the coordinates of several intermediate points. The line segment between each two coordinate points is called a "leg". Common GPS can store 20 lines, each with 30 "legs". Each coordinate point can be selected from existing road signs, or numerical values can be manually/computer input, and the input road points can be saved as a Waypoint/Landmark. In fact, all points of a route are references to a certain landmark. For example, if you change the name or coordinates of a landmark under the landmark menu, if a certain route uses it, you will find that the same change has occurred on that route. There can be a route that is' active '. The waypoints of the 'active' route are the targets of the guidance function.
