In 2.0, the only steering wheel input that the unit would recognize for controlling tuning would nudge the tuner up, not seek, nor next preset. So if you're rocking to 101.1 (Preset 1) and push the steering wheel button, you'd go to 101.3
That's not true... If you hold down the Up/Down button on your steering wheel for approximately a 1/2 second or so (rather than just clicking it) it will seek for the next station.
