Nick,

Should you have reviewed the FAQ referenced within my initial response, should the MFD be installed in a location which does not afford it an unobstructed view of the skies overhead, then the GPS signal strength may be reduced, thereby resulting in a high HDOP which in turn will in turn be reflected error in position, COG, and SOG. Operating the equipment with the boat inside one's garage, boat house, etc. will have similar GPS performance degrading effects.
