This Nav system has a few quirks. While running up from RI to Lincoln NH I was on I93 which is a straight shot all the way to Lincoln the Nav told me to exit on to I89 North which runs NW to Lebanon NH. I knew this was bogus so I did not do it. I89 runs at about a 45 degree angle away from where I was going. It quickly corrected after we passed the exit and the rest of the trip was OK. On another trip to Taunton MA it would not let me select Bay Street which is a main drag. My wife is thinking we wasted $1200 on this thing. I'm kind of wondering what will it be like when I'm in an unfamiliar area. Expected better from Toyota.
