There are many channels for the map database of car navigation system, the most important of which is the block database provided by city government agencies. For a good car navigation system, the quantity and accuracy of maps and the 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 a 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 roads or newly opened hotels to 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. Consider the storage capacity of the system.

In America, if you want to keep all the maps of the whole country, you need at least three CDs. 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, and can also be projected on the screen of a notebook computer or even a PDA. In order to adapt to different weather and lighting conditions, the image display screen must have sufficient brightness, sufficient size and good resolution.
