Hi tusharmaru,

sorry for the delay. I am very busy with my paid job at the moment.

This looks like an encoding-problem. Maybe your system's locale is set to something that is not using unicode? This is just a guess. The GPS gives you bytes of data and your computer tries to display them correctly assuming you are using en-US locale. Maybe you can try to enforce using that locale like that?

gpsString = YOURBYTES.ToString(new CultureInfo("en-US");

Hope this helps.
