The automotive GPS navigation system is an in-vehicle system that helps drivers find their way to their destination through maps and maneuvering indicators. This article presents a study on the usability of typical tasks of destination selection in three navigation systems sold in Brazil, with different data entry methods and interfaces. The research aimed to calculate the occurrence of usability problems in navigators in Brazil. Usability tests were applied to both experienced and non-experienced users in order to measure the effectiveness, efficiency and use satisfaction (usability metrics) of the three interfaces. With the tests results, several usability issues were observed in the design of the interfaces evaluated and appropriate solutions were suggested to the organization and navigation of menus and commands.
