With the rapid development of transportation, now it becomes easier and faster for people to get to different places in a day. However, there are more and more roads connecting cities and states, which make it more possible for you to get lost in the journey. All this leads to the advent of car GPS that is able to bring you a safer journey.
In modern life, car navigation is mostly based on the GPS, a space-based global navigation satellite system, which consists of a network of 24 satellites. A GPS receiver can determine your location after measuring your distance from several satellites by the calculation of signal information, as long as you stay in a place that the signal information of no less than 4 satellites can reach. GPS navigation can provide you with information of time and location so that you can pick up a suitable route to continue your journey.
In a vehicle, car gps is closely connected with a car DVD system. If the GPS system is directly built in the car DVD player, you can access car navigation easily on the player. If not, you can plug a SD card that includes a GPS navigation system with preloaded maps. The car navigation system supports many languages like English, French, Chinese, Indonesian, Spanish, and Portuguese, and the maps are available for customers in the countries such as USA, Canada, UK, Germany, France, Ireland, Norway, Spain, Portugal, Australia, New Zealand, etc. Nowadays, car gps has been widely used in different countries over the world.
The major function of auto GPS is to offer geographic information for the driver. When you enter the car navigation system, the monitor of an in dash DVD will show you an electronic map clearly, and you can zoom in or out the map so as to get a best view of location, route and nearest buildings like restaurants and gas stations. Besides, information of direction, distance, current speed and expected time of arrival can be shown together with the map as well. In addition to the useful information, car GPS is able to bring more convenience. During your driving, it can offer lane assistant, speed camera alerts and voice guidance, and help you monitor the strength of GPS signal. When using the system, you can find a location simply by postcode. You can also store some points of interest if you want, so you will access it more quickly next time.
With the beneficial navigation and convenient use, car GPS is no doubt a good friend of every car trip today. After installing a car DVD player with GPS navigation in the auto, you can find a correct route quickly when losing your direction, which saves you gas and time, and enhance the security of your driving.
