I bought this software to aid with navigation in the car (or motorhome) and while I'm pleased with the ability of the USB GPS unit to receive a signal, I'm less than pleased with the functionality of the software. You can get detailed turn by turn directions after entering a begining and an end address - but I can do that for free on the internet. What dissapointed me most was that the GPS functionality is nothing more than placing a blip on a map where you are and telling you how fast you are going (like I needed that). There's no active trip calculation - no ETA to next turn, no indicator where you are on your current list of directions, and heaven forbid if the thing actually told you there's a turn approaching (boy, we're spoiled aren't we?). It's a nice and user friendly interface but the GPS functionality was obviously an afterthought that didn't get much effort
