2010 Toyota Sienna Minivan XLE 7-Passenger 4dr Minivan (3.5L 6cyl 5A)
Navigation system defective by design
 The Toyota Sienna's navigation system has a "safety feature" which is not advertised anywhere, it appears to be the least talked about safety feature of any vehicle on the market. When the vehicle is moving, the navigation and phone hands free controls are locked out. They don't trust that passenger can safety change your destination with the vehicle moving. It was a waste of $2500.  The voice recognition system is mostly useless, out of 10 times saying "home" it only correctly registered once.  Does anyone actually like/want faux wood trim?
