Updated my navcore to 9.430 using the official TomTom Home application.
Downloaded and ran "North_America_2GB_895_4438 with Automatic Installer & Patcher" and it ran without errors.
But of course, when I turn on the device, it says the classic "You cannot use this map on this device" message.
Also tried FastActivate_03.09.2012 and it didn't help.
Suggestions?
