The GPS is the worst. Extremely user unfriendly. Many important POI's are missing. Per Toyota many were removed to make more map space. Toyota admits that the Avalon has the original GPS designed for the 2003 model. No wonder it is antiquated. Toyota will not stand behind the device. Says it was designed to specs. I've asked them to take the vehicle back and replace it with another without GPS. They consistently refuse. Suggested guidance for the same route varies. Guidance for one route sometimes goes 15 miles out of the way.
Smooth highway ride.
Get rid of the GPS until they can get it right. A 2003 version in a 2009 is criminal.
