 The gps system is effectively inoperative.  You can't get the enter key to hit a letter or other item with any sort of reliability.  Entering a street name could take twenty minutes.  The dealer here in Newark De, said that this is typical and fixing would cost a small fortune.  So I use a $150 garmin. Pathetic, don't you think?  I have about 50k miles on the car.  Also, the seat heaters stay on all the time, so I had to disconnect the fuses, so I lost that function.  I am a little disappointed in the car for these reasons.  Other than that, it has a beautiful ride with excellent mileage.  My next car will not be an Avalon - I may go to a Buick or a Lexus.
