JOSHEWAH I just got a v3 TomTom ONE, and this software is a year old but the only available software. At first I got a white screen when plugging it in, so I reset the unit with the button on the bottom. Now the unit mounts in finder and the HOME software can see the unit, but it detects it as the wrong model! The USB ID even says TomTom ONE, but the software keeps saying GO and telling me to install an update for the GO (which would probably break it). At least I can manually go in and add voices etc. but not being able to update to the latest software is a major drawback. I am going to have to install windows on VMWare to sync this thing.
