If you buy a 2007 Toyota Yaris hatchback or base sedan minus any options, you can consider placement of radio controls one less thing to worry about. However, add the optional radio or pick up a Yaris S sedan with standard audio equipment, and you’ll get mostly basic, run-of-the-mill dials and buttons, all located on the head unit with none on the steering wheel. What’s a bit unusual is the placement of the auxiliary jack, which is hidden in the lower cubby on the passenger’s side of the instrument panel.
