Use this section to provide information needed to connect your GPS unit. 

 

• COM port - select the COM port your GPS unit is connected to. These are typically a Serial port on the back of the computer. USB ports are not supported, but you can obtain 3rd party software that will make your USB port look like a Serial port.
• Make - Choose between Garmin and Magellan. 

               Magellan units must be set to a baud rate of 4800, and the NMEA string = V2.1 GSA. To do this, use the menu button on the GPS unit to set these values: press Menu\Setup\Baud Rate\4800 Baud and Menu\Setup\NMEA\V 2.1 GSA

• Select Model - Choose the appropriate model. Note that for Garmin, the models themselves are not listed, but the TYPE of SYMBOL LIBRARY is listed. We feel it's just not practical to keep up with all the models available, therefore we have used this method: the older models have a 16 symbol library, the later models have more (it varies). Choose the appropriate model, and if you're not sure, try the Other. Note that this selection only affects how the program assigns a symbol name to the point.
