Car navigation helps in providing convenience and security but if you have lack of knowledge about it, here is the complete procedure on it.
The GPS or Global Positioning System is a system based on satellite navigation which, anyone who has a GPS receiver can access freely. This space based system has proven to be extremely useful to users all over the world, including the civil, military as well as commercial users. The GPS provides information about the time and location at anywhere on the surface of the earth or even near to it. For this mechanism to work relentlessly, at least four or more GPS Satellites should be available within permissible Geo-coordinates.

Being probably the biggest GPS device manufacturer, is also available in India. The Garmin devices list is a very extensive one indeed. There is a good possibility of having on Garmin an OSM map. One can use a Garmin PND brought from the US and then mount on the External SD Card India maps. Or one can buy a Garmin PND along with Maps.

It is one of the finest softwares used in navigation which comes for free in an iPhone. This is how it works: the route of the journey has to be charted in the software. Once it is done, it starts working and tells the way, if / when the phone is not within the coverage area. It shows all the possible routes to the destination once the destination has been typed. One can select the route one wants to take after which it will highlight only the selected route. The voice system keeps giving directions on which way to turn, whether right or left, and also if the vehicle has taken the wrong direction or path. This helps the motorist to concentrate on driving without looking at the phone screen repeatedly. The feature to be highlighted here is that even if the motorist diverts from the proposed route, it first prompts that a wrong route has been taken. Yet, if the vehicle continues on the same diverted path, the software adjusts itself automatically and takes the new route. Finds out the alternate route to reach the destination, and also display the newly selected route, all automatically!
