Hi i´m from Portugal and i´m searching for a device low cost who cans interface with
a external gps antena, and it works with a program that runs on win os the program is racechrono(on www.racecrhono.com) can you help me?

I understand that this device is for world wide use.
But how would you upload different maps. I tend to go back and forth from Europe and the United States.
