I bought my TomTom One in winter 2008, I think. I LOVED it. It took me all over the United States with BBC Announcer Roddy giving me directions. As someone who gets lost backing out of the driveway, this device has been invaluable! Last week, I plugged my device into my computer and got a "critical update" message, and allowed the update into my device. HUGE MISTAKE! When I tried to operate my One through the TomTom portal, it was grayed out and I got a prompt that this feature was no longer available to me since the software wouldn't allow map updates, BUT that my TomTom would still operate as usual - what a big fat lie. After that "critical update," my device can no longer receive a signal. Had I not done that critical update, I would still have a usable device which would get me where I need to go. I am very unhappy with TomTom for the way this was done. I need a gps system so I got online and searched purposely for makers OTHER than TomTom. Had my device just given out on its own, I would have bought another TomTom. However, I used my device the week before this "critical update" and it immediately became a paperweight after that update. Shame on you, TomTom! I trusted that update you deemed "critical." I won't be buying any of your products again.
