I have an 2008 TL NAVI. I have question about what others are getting on traffic info. I can't seem to scroll to any other city and see the traffic info. I can see all info for Pittsburgh which is 100 miles west of me, but when I scroll to DC. I see no traffic info. If I scroll to LA. I see no traffic. Does this only work if say your 100 miles from the a city. Just curious how others are working.
