 Know that you will still need to have your garmin on your dash. Many of the Navigation systems features won't work unless you STOP THE VEHICLE. I WOULD NOT HAVE PURCHASED IF I HAD KNOWN THIS.  BEWARE.   Also, the engine turns off at stop lights. This feature must be disabled EVERY TIME YOU START THE CAR. IT CANNOT BE PERMANENTLY DISABLED. THIS VEHICLE HAS TOO MANY NANNY FEATURES THAT CANNOT BE TURNED OFF.Update, 8-7-2017The vehicle is now 4 months old. The radio/navigation system died today, 6 days before we are to drive the car to Florida for a vacation we have planned all year.  The dealership says the entire radio and nav display must be replaced and the parts won't be available for 3 weeks.  They gave me a national number for Toyota.  They said to go to different Toyota dealerships to see if the parts are available there.  They said the dealerships don't share parts.  I bought the platinum service agreement and a 6 year prepaid maintenance plan; all apparently worthless.  I deeply regret buying a Toyota.  It is a mistake I will never make again.  I will trade in this garbage as soon as I am financially able to do so.
