On the previous page, we suggested that the Aveo’s radio was about as simple as simple gets. We lied. In actuality, the Aveo’s climate control system makes the radio look like a collaborative project between NASA and Einstein. To keep occupants comfortable, the Chevrolet Aveo uses three dials – one for temperature, one for fan speed, and one for mode – and three buttons dedicated to a/c, recirculating the cabin air, and activating the rear defrost. Each of the buttons and dials feels up to the challenge of repeated use, though we’d prefer a rubber grip on the center dial to match the one used on the radio.
