Given the time of day and mood, some days I tend to listen to music loud with the windows down.
Entune maintains different volume levels depending on the source. So I was listening to XM on my way home a few days ago and blasting the music but switched to FM which was playing at a much much lower level, a few mins before getting home. My wife decides to take the 4runner to work today and decided mid drive to swich to XM and it scared the hell of her.
serves her right to mess with Entune and how well it's built
