Subject says it all.
The Entune radio in my 2016 Avalon Limited does not mute when the factory Nav system gives spoken turn by turn directions- thus making them hard to hear/understand them.
Dealer can't fix and Toyota USA says this feature is not available on their technically and electronically advanced top of the line flagship sedan.
On most cars I've driven, the radio mutes for spoken directions on a factory nav. Does yours?
Are they feeding me a line-- or did they drop the ball when they designed the system?
