In this tutorial, we learn how to operate the audio system of a 2010 Prius. Every Prius comes standard with a 6-speaker AM/FM tuner with a single CD player. There is an 8-speaker with 6-disk changer available as well. The top of the line comes with a premium auto system and a navigation system. The left hand knob switches the system on and off and controls the volume. To set a radio station, use the manual knob and press it down until you hear a beep when you find the station you want to listen to. This is an easy system to learn that is great in any Prius!
