Well, it's better than the old version, which was well outdated even last year.
This Version, 126.96.36.199, works somewhat, however some things don't work at all. Still no computer control of my TomTom ONE LE, just an error that says "this feature is not supported by your device or operating system..." This means that it is not possible for me to password protect the gps. (If they can't figure out how to make the computer-gps control work out, they should make it possible to password protect the gps from within.)
Some of the new Home program works, but more often than not, the updater fails. Also on the main home page, it tells me that my MapShare updates are out of date (which they are), however it won't let me update the MapShare corrections. It directs me to the update page, which after a minute says that everything is up to date. (To date, I've never gotten any mapshare correction updates!)
I'm still happy with the TomTom ONE as a standalone device, but their support for OSX users is inexcusable.
