No drivers needed for GPS device, pretty much plug and play.
Agree with FreeScan. With you being a premium subscriber, you can use FreeScan to download the programming "stuff" for your desired system(s) to your scanner, which would include location information. That location information and the GPS device work hand in hand to turn "things" on and off depending upon your location.
Lastly, you'll need a USB-1 cable, which connects from your computer to your scanner from programming purposes. When you get that, there will be instructions where to download the latest drivers. Be sure you download and install these drivers BEFORE plugging in the cable the first time.
