VS 
The Motorola H700 vs the H300.
Pros: Fast satellite acquisition and amazingly strong receiver (I acquire satellites indoors where most GPSs fail), fast route calculation, ability to manipulate routes, entertaining voice customizations, solid, reliable operating system, stable suction cup bracket (no shake) that fits nicely in car.
custom routes (the TomTom doesn't have this feature) and by using it correctly, I find I can create the route I like much faster than creating one manually (as I did with previous GPSs). Don't be fooled by the Itinerary feature. You can create an itinerary but navigating the waypoints is done manually - you select the next one to go to once the previous is reached.
