2. MX575 Mounting
The preferred orientation for the MX575 D/GPS Satellite Compass is parallel to
the axis of the vessel. In other words, it should be pointing towards the bow of the
boat. This mounting configuration will provide the ability for the MX575 to output
the positioning, heading and pitch of the vessel.
Mounting it perpendicular to the axis of the vessel is also acceptable and will allow
calculation of the roll of the vessel. The MX CDU has an offset option to
compensate for orientation errors.

Mounting Orientations
If a gyro compass is available, this could be used as reference to calibrate the
physical heading of the MX575 and its corresponding heading measurements to
true heading of the boat by entering a heading offset (refer to pages 34-37 of this
manual). For example, if a gyro compass heading provides 183.2° while the
MX575 provides a heading reading of 184.0°, a bias of -0.8° (the bias is added)
