Navigation function
1. After the user marks any two points on the car GPS navigation system,
the navigation system will automatically design the best route for the car owner
according to the current location. In addition, it also has a modification
function. If the user does not take the best route recommended by the on-board
GPS navigation system because he accidentally misses the intersection, and the
vehicle position deviates from the best route trajectory by more than 200
meters, the on-board GPS navigation system will location, redesign a route back
to the main route for the user, or design an optimal route for the user from the
sexual location to the destination.
2. Turn to the voice prompt function
As long as the vehicle encounters the intersection ahead or turns, the
vehicle GPS voice system prompts the user to turn and other voice prompts. This
will prevent the owner from taking detours. It can provide the whole process of
voice prompts, and the driver can realize the whole process of navigation
without observing the display interface, making driving safer and more
comfortable.
3. Add point of interest function
Since most cities in our country are in the construction stage, new
buildings may appear anytime and anywhere. Therefore, the update of electronic
maps has also become a concern of many consumers. Therefore, if you encounter
some target points that are not on the electronic map, as long as you are
interested or think it is necessary, you can add the point or new route to the
map. These newly added points of interest, like any original point on the map,
can be applied to functions such as electronic map viewing.
4. Positioning
GPS can accurately determine its position by receiving satellite signals,
and the position error is less than 10 meters. If the machine has a map, you can
mark the corresponding position on the map with a mark. At the same time, GPS
can also replace the traditional compass, display the direction, replace the
traditional altimeter, and display information such as altitude.
5. Speed measurement
Through GPS receiving and calculating the satellite signal, the specific
speed of driving can be measured, which is much more accurate than the general
odometer.
6. Display track
If you go to an unfamiliar place and someone leads the way when you go
there, don't worry about what to do when you come back. GPS has a track record
function, which can record the route your vehicle travels. The accuracy is less
than 10 meters, and it can even display two difference in lanes. When returning,
the user can activate its return function and let it lead you home smoothly
along the route you came from.
