REFERENCE
The ‘Wrap’ option allows
the GPSMAP 195 to contin-
ue storing track log data
after memory is full. The
oldest track log data is con-
tinuously overwritten with
new data in an infinite loop.
To utilize the TracBack
feature, you should clear
the track log before leaving
the departure airport.

TRACK LOG
The
track submenu
lets you specify whether or not to record a
track log (an electronic recording of your path) and define how it is
recorded. It also provides an indicator of the track memory used and
selects functions to clear the track memory and start a TracBack
route. The following functions are available:
•
Record Mode
— lets you select one of three track recording
options:
• Off– No track log will be recorded.
NOTE
: Selecting the ‘Off’ setting will prevent you from using the TracBack
feature.
• Fill– a track log will be recorded until the track memo-
ry is full.
• Wrap (default)– A track log will be continuously record-
ed, wrapping through the available memory and replac-
ing the oldest track data with new data.
•
Interval
— defines the frequency with which the track plot is
recorded. Three interval settings are available:
• Time– records track plot based on a user-defined time
interval.
• Resolution (default)– records track plot based upon a
user-defined variance from your course over ground.
The resolution option is recommended for the most
efficient use of memory and TracBack performance. The
distance value (entered in the interval field) is the
maximum left/right deviation allowed from the last
defined ground track before recording a new point.
• Distance– records track based on a user-defined
distance between points.
•
Interval Value
— defines the distance or time interval used to
record the track log.
•
Delete Track?
— allows you to clear the track log currently
stored in memory.
•
Start TracBack?
— converts the current track log into an
inverted route and begins route navigation along the track log.
To reset all track options to the default settings:
1. Press the

key, followed by
