New TT One (New Version) user here.\r\n\r\nI have had NAV in my cars for some time now: Pioneer AVIC N1 and stock Ford. I got lost for the last time on a business trip last week. Stopped into the nearest Circuit City and solved that problem with TT and a carrying case.\r\n\r\nI am impressed so far. Navigation is spot on, SunTime takes care of the day/night mode.\r\n\r\nWhen I check for updates it says the server is not available. I hope this is a temp problem.
