Simply load the GPS driver, plug the GPS receiver into your computer’s USB port and install your own personal mapping software to begin to view your position in real-time in relation to the surrounding streets in your travel area.
NOTE: From within your mapping, or navigation software (including the supplied GPS Information utility), you will need to manually configure the selection of the COM port to what was assigned to the GPS receiver so that proper communication between the GPS receiver and mapping program can occur. Most all software requires that you manually configure the COM port setting for any GPS device you use.
We strongly suggest that you first test your USB GPS with the included GPS Info utility program to confirm that the GPS receiver if functioning properly on your PC and that you have successfully configured the right COM Port setting. Once this has been done, close the GPS Info program and start your application for COM port configuration.
