Navigation computer for motor vehicle

The housing (3) of the vehicle gyroscope can be angularly adjusted in the navigation system housing wall. To this end the gyroscope housing has two sprung tongues (5, 6) that extend radially outwards and upwards from the top of the housing so that they can engage in openings (7, 8) in a circular type rotating coulisse (9, 10) which acts as a support for the mounting tongues (5, 6).
