Car GPS 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 drivetrain (a system of dynamics), a gyroscope and an accelerometer can be used for greater reliability, as GPS signal loss or multipath can occur due to urban canyons or tunnels.
Aftermarket GPS system
A number of manufacturers supply aftermarket GPS navigation devices that can be integrated permanently into the vehicle. A typical location for such an installation is the DIN slot for the radio / tape / CD. However, in extreme cases, the dashboard may also be remodeled to accommodate the unit.
This approach can be considered a tradeoff between the previous two options. Benefits include a more secure and better cosmetic finish than a portable device, and lower cost compared to the installation of an original factory-supplied GPS.
