5. Overland Navigator has complete support for APRS symbols, including the most recent overlay
symbols. The symbols were designed from scratch to be consistent, high contrast, easy to read,
and easy to distinguish from non-APRS waypoints (round vs square).
Instructions for setting up Overland Navigator with a Kenwood D710, Argent Tracker2 Model T2-301, or
an Argent OpenTracker+ are available in Appendix D: APRS Setup. As users configure additional
devices, we’ll try and include the instructions on our website.
To setup APRS on another device:

Purchase a radio or tracker that can output heard stations to a GPS; preferably one that supports
the $PKWDWPL sentence type. $GPWPL will also work, but all stations will use the same icon.

Connect a cable from the Overland Navigator PC to the GPS input connection of the APRS device.
You’ll know you have it right when your APRS device indicates that it has good GPS input.
Assuming a DB9 serial connector for the PC side, wire the cable up to a connector that matches the
GPS port of your APRS device. Use the following as a guide:
PC (9 pin D-SUB terminal)
GPS
DB-9 pin 5
GND
DB-9 pin 3
Rx (Receive)
DB-9 pin 2
Tx (Transmit)

Configure the Overland Navigator NMEA Interface port and baud rate settings to match your APRS
device settings.

Configure the Live Waypoint Expiration setting to something you find reasonable. This value
controls how long an APRS waypoint will be displayed before being removed from the map. It will
fade throughout its lifetime.

Configure your APRS device following the manufacturer settings.
Keyboard Control Input
Most Overland Navigator functionality can be controlled via the keyboard. The keys used to execute an
Overland Navigator action are configurable via the Settings application. See Appendix A:
