A must have for me which has replaced my "passive" car gps is
Waze which makes gps in your car interactive & social.
It's a cool social GPS driving and navigation app that connects you to other drivers.Waze is a fun, community-based traffic & navigation app, 30 million strong. Join forces with other drivers nearby to outsmart traffic, save time & gas money, and improve everyone's daily commute.
With community-generated real-time traffic, you'll always get the best route to your destination. By simply driving around with Waze open, you're already contributing tons real-time traffic & road info to your local driving community. You can also actively report accidents, hazards,
police and other events you see on the road, and get road alerts coming up on your route too. Find the cheapest gas station along your route with community-shared gas prices.
