What tomtom has itinerary planning?

Go-550 Live (UK&ROI)
Go-750 Live (Western Europe)
Go-950 Live (Western Europe & North America)

Note with the 750 Live to get the new map installed to it in full you will also require to purchase a MicroSD card or at least 4GB (class 6 or higher) - Mike

I've looked at the Go-550 Live and it sounds like the best one. I just want to check though am I able to update the map on this model if whenever I decided to do so?

There is no problem with the map size on the 550 Live so update it within 28 days of purchase as your first update is free - Mike
