I'm getting my prius in a couple of months and I was wondering is there a function in the car to increase/decrease the bass? if not how could i go about doing that if i'm using my ipod connected through the aux.
Yes, if you push the audio button on the left side of the display, than on the screen push on the button "Sound". You can adjust bass, treble, left-right and front-behind balance. You can also switch on ASL (Automatic Sound Level) which increases the volume slightly if you drive faster.
