The GNSS Compass should be aligned such that it is level with the vehicle and the indicator on the lid is directly forward of the sight, see GNSS Compass alignment. The sight can be used to visually align the indicator for best results. See Alignment on a boat for example mounting on a boat and Alignment on a car for example mounting on a car.

GNSS Compass alignment

Install the unit such that the X+ axis points forward towards the front of the vehicle and the Z+ axis points straight down towards the ground as shown below.

If aligning GNSS Compass with the vehicle axes is not possible within vehicle size or shape constraints, it may be mounted in a different alignment and the alignment offset can be configured Using the Web User Interface or Using GNSS Compass Manager.
