	An '''automotive [[Navigation System\|navigation system]]''' is a satellite navigation system designed for use in [[automobiles]]. Unlike other [[GPS]] systems, these use 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]] and a gyroscope can be used for greater reliability, as [[Navigation System\|GPS]] signal loss and/or multipath can occur due to urban canyons or tunnels.
