One of my minor beefs with my WRX is the lack of actual interior temperature setting... it only has the ol' school hot/cold air mix knob.

Does anyone know of an interior mod for this - you know, something I could dial in "72 degrees" or some such thing" - at least for a 2004 WRX wagon? I understand the Saab 92-X aero had such a system. Would that work in the WRX?
