Hi guys. I've been chatting with Littlejohn and we can't work this one out. What exactly is needed for the I3 that would allow for usage in the US? The Garmin site isn't as GPS numpty (that's me, I get so confused on there) friendly as the TomTom.

I assumed that the City Navigator North America V8 would work, could anyone help shed some light to help save what's left of my barnet?

Thanks in advance guys.
