If no GOTO or follow is in progress, the steering instruction is NO TARGET, no steering arrows are shown, but the rhumb line indicator is shown.
The graphical XTE indication places arrows either side of the rhumb line indicator and pointing towards it, dependent on the value of XTE. The first arrow is shown when the XTE reaches 0.01nm, the second at .05nm and subsequently at 0.1nm intervals .
Note: The steering instruction and graphical XTE indication are repeated on all

Textual data provides Position, SOG, COG, Bearing and Range to waypoint, Time, Fix status and the XTE indicator. Any unavailable data is replaced by dashes, one per character. When there is no GPS fix but there is a value for the last fix, this is shown instead; POSITION is replaced with LAST POSITION.
The (c) indicator only appears when the position has been user calibrated.
The Fix indicator shows the GPS Fix status and indicates either FIX OK or NO FIX. In the case of a differential fix,
Note: Graphical XTE indicator is as per Waypoint data screen, see above.
