2014 Toyota Avalon Hybrid Sedan Limited 4dr Sedan (2.5L 4cyl gas/electric hybrid CVT)
Deficiencies - annoying
 Update:  NAV system is a misnomer in my opinion.  There have been no software updates since the software was launched in 2013.  Roads change, but Toyota has no updates, thus accuracy is absent.  Basically, I have a map that shows others generally where we are.  My new TOMTOM GO600 is my "real" NAV system.Gas mileage is good -- north of 34 mpg overall.  Adaptive speed control is super.  My Parkway Toyota service center  (really the staff) is a delight.= = = = = =NAV system is primitive compared to my five year old  TomTom.Theres no 3D, there are no traffic light cameras and there is no display of current speed limits.Programming the NAV is tedious.In seven years the NAV system has moved ahead one year in its development [see below].Further, the NAV system voice even at the lowest level #1 is much too loud; and there is no way to lower the volume, save disabling all sound.It is far louder than my 2007 Toyota Avalon Limited at sound level #1.There is a plastic chrome bezel around the instrument cluster.When sun hits the bezel, it is most distracting.Dealer team says thats the way it isUgly situation.
