Hassan You need to read data from the serial port. The best way to do this is through the timer event. The next task is to check whether you have a GPS fix which is determined from the 'RMC' sentence code in the NMEA string. If you have a fix you can then read the 'GGA' sentence code to extract the Lon/Lat of your location.
You might care to visit http://home.mira.net/~gnb/gps/nmea.html. This site gives a good explanation of the NMEA data strings. Hope this is of some help, happy coding!

We want to be program a button on our custom ipaq application, that will get from the GPS the X,Y coordinates of the current waypoint. Do you have an example of the source code.
