Summary: On paper the 8100T seems like the ulitmate navigator, but the unreliable voice recognition and incomplete topographic maps give us pause. Some may prefer the Navigon 2200t ($229), which has a smaller 3.5-inch display but also offers lifetime traffic and the excellent Reality View Pro and Lane...
Excerpt: GPS is supposed to get you where you want to go. The Navigon 8100T does deliver on its promise of no wrong turns and the occasional Dairy Queen pit stop. However, at $600, it seems the poor house is a little too high on this unit’s points-of-interest list.
Pros: Bright, touch-sensitive screen provides a nice pretty 3-D picture. Side volume controls allow you to hear clearly, without veering off the road.
Cons: Lag time slow enough to incite road rage. Slow start up. Some destinations out of date.
