The TomTom 335S GPS navigation unit has a nice sleek look, wide-angle screen and a brite, dynamic display. On balance, for the money, it's an excellent choice for general trip planning and in-town commuting. But it does have some issues that make it less than ideal. None are necessarily deal breakers, but taken as a whole, they prevent this GPS device from being a slam dunk.
The interface is clean, with easy to understand icons and a logical menu system. But the touch screen itself is a bit slow to respond and the buttons are cramped, making it difficult to quickly input destinations. That said, once an address has been entered the device calculates routes quickly and efficiently. The points of interest database is extensive but the search results are returned as long lists of names with no other information such as street or city, making it difficult, for example, to locate a particular food chain in a neighboring town.
In fact the 335S has a built-in system known as IQ Routes which relies on anonymous user data (gathered when connecting the device to the internet via your computer) to provide more accurate time estimates and better navigation based on traffic patterns and actual speeds. The other nice feature is TomTom's Lane Guidance technoogy which offer better visual cues when navigating complex intersections and highway interchanges.
But there are a number of features I don't particularly care for. The graphics on the 2D and 3D navigation screens have no special visual appeal to my tastes, though their functionality is perfectly fine. I also have some hardware concerns as well. The power connection that runs from the cigarette-lighter to the bottom of the unit is especially difficult to snap into place, with a deep groove that felt like sticking a square peg into a round hole. And to actually snap the unit into the suction-mount felt like either the screen or the brackets in back were going to break off from the required force.
