Highway Mode

You can use the device to navigate on land in highway mode.
Select Highway.
Sail Racing
You can use the device to increase the likelihood that your boat
will cross the start line of a race exactly when the race begins.
When you synchronize the race timer with the official race
countdown timer, you are alerted at one-minute intervals as the
race start approaches. The device uses this data to indicate
whether your boat will cross the start line before, after, or at the
correct time to start the race.
Setting the Starting Line
The sail racing start line guidance window is added to the sail
racing profile by default.
1 From the sail racing screen, select MENU.

Select an option:
• To mark the port and starboard starting line marks as you
sail past them, select Ping Port and Ping Starboard.
• To mark the port and starboard starting line marks by
entering their coordinates, select Enter Port and Enter
Starboard.
• To switch the position of the port and starboard marks
after you have set them, select Swap Port&Starbd.
• To compensate for the difference in the physical location
of the GPS and the bow of your boat, select Bow Offset
and enter the distance.
Instruments
The instruments page displays data such as wind speed,
temperature, and wind direction, provided by sensors connected
to the device using a NMEA 0183 network. The data displayed
