Real Time Tracking With Laptop in GPS technology and devices Posted October 13, 2004 I have recently "procured" a copy of Mapsource and uploaded it to my laptop. I was wanting to use a feature in Mapsource that allows real time tracking of the movements by hooking a cable to my Garmin Vista to the laptop. However, the cable supplied with the Vista has a female serial port. There is not a serial port on the laptop. I got a male serial to male parallel adapter from Radio Shack to hook up to the laptop and it did not work. Radio Shack also sells a serial port to USB converter cable but it is $42.00. This a lot of money to spend for it not to work. I realize I can return it but thats a hassle I want to avoid. My first question is...can this be done. It works on my desktop computer while sitting in the house (I actually get satellites in the house). But that is because the desktop has a male serial port on it. My second question is, if it can be done, what kind of cable or adapter is needed to do this? Any assistance is appreciated.
