I recently purchased a 2015 Lexus CT200h F Sport w/the Nav package. I love the car, but the one frustration I have is this: when I go to the Audio screen (to change stations, etc.), after a few seconds, the screen goes back to whatever was on the display previously, be it the map (usually), or the fuel graphics, etc. Is there a way to make the audio system the default view? I can set up the "home" screen with audio and the map (or whatever), but that is a split screen. Is there something wrong with my system, or is this normal? Thanks!
