Gas stations and other layers can be added to maps.

The bottom right label shows the street you're on; the top shows your next step.

The iconography in Google Navigator is strong

Landscape view with satellite maps active. The traffic on the route is red, indicating slow flows. The time to arrival is 6 minutes. Clicking on the icon for traffic brings up the traffic view, a zoomed out birds-eye look at your entire route.

OK, when you're close to your destination, Google Navigator shows you your final waypoint on a streetview image. Neat!

It also shows you turns in streetview, too. Useful for navigating tricky intersections, but we'll see how accurate the system is at parsing streets on images and correctly drawing arrows over them.

Traffic incidents shown on traffic mode. Traffic data is aggregated from multiple sources, as with Google Maps. That means local road authority systems like caltrans here in SF, and crowdsourced from handsets that are running Google Maps and Navigation apps.

You can search for business or location names exact addresses by text or voice search. Soft queries, like "that museum with the king tut exhibit in San Francisco" which will bring up a suggested list of locations you may want to nav to.
