2010 Toyota Sienna Limited 7-Passenger 4dr Minivan (3.5L 6cyl 5A)
I paid two grand more to get the nav system. It is horrible. It almost got me killed once when my wife and I had to pull over in busy traffic to reset it. Toyota will not allow the passenger to use the nav system while moving. They are the only nav system that does this to the consumer, and it ruins the car for me. I now use my iphone for nav. Also, nav can only be updated every two years or so, meaning restaurants are incorrect and highways changed. Plus, they charge you $260 bucks for the upgrade when it does come out. There are a million complaints online about this nav system. Don't buy this van!
Sign with tomtom or some other real nav system. Or go to a satellite upgrade, so the system is always updated. Toyota / Lexus needs to let the driver operate the nav system, and make the vehicle safer to drive. Pulling over is illegal, and dangerous.
