I have a 2016 Highlander. Whenever the vehicle is not used for and hour or more and then started, the radio is off. Every other vehicle I have owned the radio will be on the station it was on when the vehicle was turned off. I have to turn the radio on every time I start the Highlander and then tune to the station that was on when I turned the vehicle off. Any help/ideas to resolve this would be appreciated. thanks
