I have use this device for over a month now , and damn I do not like it . I live in NYC and I want to know the traffic situation on the street . it be terrible wrong all the time , and after I be stick in traffic it tell I that the highway be congest , but only with a few minuter delay ... I be stick on FDR for 30 minute and it tell I it be a 3 minute delay . it do not show the local street info , and hardly the highway , so the traffic information be understandable free as it this terrible . I always have to use a separate phone to see the traffic status on google map as it be always incorrect . I have never ever be close to arrive on the esitmated arrival time as well , it be over 25-50 % incorrect on the time of arrival , especially as it do not understand that it will actually take time to stand still at a traffic light . do not calculate that into the estimate arrival time . when be suggest the fastest route it do not suggest highway , it be use local street , and as I describe above , do not calcualte time for the traffic light . I go to the beach and be suggest a 1.05 h travel time , it take I 2 hour to get there with this device . I go on the highway as I know they and it take 1.10 h in travel time , and it be congest at that time . on other device you can select to drive on highway only if possible . it alternate the road in the middle of the driving , and send I off in the wrong direction , and then it tell I to make a u-turn to go back to the road I be drive on from the start . it be just full of these annoyance all the time ... it do not suggest alternative road when it calculate a road . miss exist as it tell I to keep to the right and then the exit be on the left . so in over all . I hate the device , and hate be a strong word .
