Summary: Good: The Navigon 2200T offers free real-time traffic updates for life as well as text-to-speech functionality and reality view for major highway exchanges. Bad: The screen size is rather small. Satellite acquisition is slow. The Navigon 2200T can be the handiest and useful tool for the traffic updates and also the text-to-speech option makes the driving easier and comfortable. The device can be blissful for the highway runners.
Pros: I just bought a slightly old Navigon model and love the hardware.
Cons: Here is the big warning--Navigon does not provide a free update to maps and POIs. If you happen to buy a unit that is at the end of its product life span, be prepared to fork over an extra $80 to get new maps.
