Just jumped ship and traded my 2006 Prius with 141,000 miles for a 2012 certified pre owned Prius Four with 35,000 miles. Question, How do you adjust the radio volume to auto lower when the Navigation is giving instructions? Currently if the music is loud, you can barely hear the Navigation instructions and the volume on the nav screen is ALL the way up. Is there a way to make the Audio volume auto lower when the Nav is being used? Thanks for the advice in advance.
