The main difference between the 730 and 930 model is the map coverage (the 730 is US and Canada only while the 930 includes European maps) and the addition of "Enhanced Positioning Technology" on the more expensive 930.

Both the 730 and 930 are available with traffic receivers (GO 730T and 930T for receiving real-time traffic data).

So what exactly is IQ Routes and how does it work? IQ Routes are based on average speeds measured on roads, rather than posted speed limits. This means that the new TomTom GO determines the best route to take based on recent historical data. According to TomTom, "in almost 50% of all journeys, this results in a faster route."

Advanced Lane Guidance provides users with realistic representations of complex highway junctions and lane-specific visual directions.

TomTom says the new models will sport a glossy new finish on the case, and have an updated interface with new icons.
