GPS Speedometer is an attractive speed meter on the car dash for Windows Mobile phones.
Make sure you have .net framework installed. The setings.exe included in the attachment is from the Microsoft SDK samples, which can be used to set the COM port if you dont' have any other application.
This has been tested in
HTC P3300 (Artemis) and
HTC TyTN. Give a try and let me know if it works for you.
