any aftermarket HU that works with the buttons on the wheel?

According to this, Pioneer and Sony's that have optional remotes have an input. This module goes between the steering wheel controls and the radio. From what I'm reading though, your heat controls may not work. Not sure though.

All middle-to-high-end Eclipse head units support the wheel controls.
