What a super device! And the free software updates are working great. It's only a matter of a one-time download/install of the Update Manager software and I am notified with a desktop pop-up; from there it's a simple click followed by another click and it's a done deal. I've done one software system upgrade and two map upgrades so far. The speed and accuracy of the unit is unmatched.
I like the voice giving directions but especially like the confirming 'ding' for making a turn and the fact that it pinpoints the location of the car/person (in walking mode) within six feet.
Last, but FAR from least, is the Amazon pre-purchase support I received. I never used the option before thinking it was just another point-of-purchase gimmick but I did call the toll free number that appeared on the web page (it's not always there because the experts are not always available) and proceeded to have a great conversation about several manufacturers, units, codes and their designations, etc. Wow, what a real expert he was and he had 'test driven' this unit with several competing brands for a hands-on, real-time experience. He did NOT work on a commission basis and gave me his number for any follow-up questions, concerns, problem resolutions and post-purchase issues. This new, free service far outweighs the fact that Amazon is opening a store in my state at the end of the year which means they will be including state tax at that point.
Summary: Great Price; Great Unit; Great Online Seller.
