May I know if anyone here can teach me how to use this GPS receiver (Garmin GPS 18 LVC, http://www.garmin.com/products/gps18oem/) ? I'hv no idea how to configure it and use it properly. I tried one of the software that I got from its website (www.garmin.com) but I would like to use a simple serial communication application to send command to and receive data from this GPS receiver. I dont understand why I need to set the longitude and latitude in the Garmin software application since I was expecting to receive the location information from GPS.
Can anyone teach me?
