I just saw this a minute ago in another Forum. I did not read the short FAQ or investigated about models and NavCor versions.Technically, you can't use the itinerary feature with the One v3. But users were able to do a hack by creating a custom menu. But then, TomTom put out the v8 firmware which removed this possibility.
So, yes, it is possible, but you have to create a custom menu and you must stick with v7 firmware. A search of the forum will show you how to make a custom menu for this purpose.
