I have a laptop on which I'm running Microsoft Streets & Trips 2010. I'll be taking the family on a 1500 mile round-trip road trip in about a month. I was thinking of getting a USB GPS locator/receiver so that I can use the laptop with Streets & Trips as my navigation system. I've looked on eBay and see a lot of listings for Streets & Trips with the GPS locator/receiver. Does anyone know if the locator/receiver is tied to the specific version of Streets & Trips that it came with, or if I pick one up with an older version of Streets & Trips, will I be able to use it with the 2010 version that I already have installed?
