I'm planning on coming along on the convoy to Nissan on Sunday, any ideas on how to get a .itn file working on a Tomtom 3rd edition as there is no menu option for this as far as I can tell.
I usually open the tomtom as a usb thing in my computer, in there is 6 or so files. 1 should be itn files, drop yours in there. then when you switch on tomtom go to itineray palnning load then whatever its saved as
