A navigation assembly (5l) for mounting a navigational device (10l) in an open port (12l) of a vehicle resulting from removal of a non-navigational component is provided. The navigation assembly (5l) broadly comprises a mounting assembly (218l) and the navigational device (10l). The mounting assembly (218l) is mounted within the open port (12l), and the navigational device (10l) is fixedly or removably attached to the mounting assembly (218l), such that the navigational device (10l) may be linearly raised or lowered between two viewing positions that are in a general linear relationship to each other. The navigational device (10l) is operable to pivot left and right within the open port (12l). Additionally, a navigation assembly (5m) broadly comprising a mounting assembly (218m) and a navigational device (10m) for raising and lowering the navigational device (10m) among three viewing positions that are in a general linear relationship to each other is provided.
