What is it systems in cars and navigation ? An automotive navigation system is a satellite navigation system designed for use in automobiles. It typically uses a GPS navigation device to acquire position data to locate the user on a road in the unit's map database. Using the road database, the unit can give directions to other locations along roads also in its database. Dead reckoning using distance data from sensors attached to the drive train, a gyroscope, and an accelerometer can be used for greater reliability, as GPS signal loss and/or multipath can occur due to urban canyons or tunnels.

this is a gps.

One issue is that people are dependent on technology to tell them where to go instead of asking someone for directions to their location. Another is that a gps may not pinpoint the person to the exact location they are looking for. one other issue is that the gps can take your current location from device and upload it to the web without the person knowing.
