Just got a ct200h premium, following years of BMW and recent Infiniti! So far, so good except the navigation appears to be slow to anticipate turns, and if you pull into a parking lot, or other place off course, it takes too long to get you back on course. There does not seem to be any user function to speed it up? In addition, sometimes it will register ****** for approaching street names, and until its on the street, the name will not appear??? Anyone else having theses issues, or is this the way Lexus Navigation works???
