I bought a TT1 V3 for my son and myself. I have come to the conclusion, unfortunately, the the route determination ability of the unit is so poor I must return it. Here are some facts and observations:
I let the unit select my route from work to home, a 50 mile trip (fastest route preference). This trip, involves only 6 turns. Of these 6 turns, the unit made errors on 4 of them:
1. Told me to make a right, then make a U turn, when I could have easily made a left. It seems this unit likes to try to have you avoid left turns, even at the expense of time/mileage.
2. At one point, it told me to turn left into a canyon. If I had done that, it would have added at least 1 hour to may otherwise 50 minute commute.
3. It wanted me not take a freeway, which was the most direct route, and go a longer route on surface streets. This would have added 6 miles and about 15 minutes to my commute.
4. It told me to take a loop near my destination, rather than turn left, adding 5 minutes and 3 miles.
I do not understand how the TT1 can have such bad route algorithms. It really seems incomprehensible some of the choices it makes.
I really wanted to like this unit, but unfortunately I am going to get a Garmin. My wife has one and it does a great job in routing.
