For a good car navigation system, the number of maps, the accuracy and timeliness of data are very important. No matter how accurate the coordinate position provided by GPS is, if your navigation system can't provide a map of your area, or the provided map is wrong, your system can be said to be worthless. Therefore, when purchasing the vehicle-mounted satellite navigation system, we should pay attention to the following matters: 1. Check the accuracy of the test system, choose one or two familiar road sections or newly opened hotels, and see if the system can accurately display the location of the car. Because streets and road sections are always changing, your system must also provide regular update services. 2. Considering that the storage capacity of the system is in the United States, at least three CDs are needed to save the map of the whole country. Therefore, the car navigation system must also have a correspondingly large hard disk memory. 3. Image display The image display of the car navigation system can be installed on the dashboard of the car, or projected on the screen of a notebook computer or even a PDA. In order to adapt to different weather and lighting conditions, there must be enough brightness, enough size and good resolution under the image display screen.
