VZ Navigator 4 was a great product that surpassed in usability and capability of many standalone-GPS devices I have seen. VZ Navigator 5 is worse than current standalone-GPS devices.
Useful features in 4.0 included:
1. 2-D page view of directions that allowed quick view of future steps
2. Quick view of trip summary by going back one step from the current position and quick return to navigation by one button click
3. Easy to use green, yellow, red traffic indicators
4. Quick pick for “Home” and “Work” on the navigation menu
In VZ Navigator 5, these features are gone. The tool is significantly degraded in usability with the new version. I recommend all decision makers involved in VZ Navigator 5.x be removed from future VZ Navigator projects and that 4.x be redeployed as an upgrade IMMEDIATELY!
