Im loving the Avic. The Navtraffic is actually pretty useful in the DC metro area. I leave work, get outside the building, and immediately check the traffic info, and check the color of the roadway for the trip between Bethesda and College Park. If it's red/yellow by Connecticut ave exit? I take the backway. If its green? I hit the Beltway. It's been fairly accurate lately. Last week was heading to northern Baltimore. I95 north was "red" just outside of Baltimore. I didnt believe it. Got off the BW Parkway, headed across 695 to I95 north. DEAD STOPPED TRAFFIC. Slipped across 4 lanes and made it to a random exit and let the Avic reroute me back to the Parkway north. Gotta love it.
