I was wondering if it was possible to swap out head units on my 2003 accord in order to upgrade to automatic climate control. I have a 2003 Ex and the head unit I wish to install is also from a 2003 Ex. Would this be a simple installation or impossible. I had read on another thread that is impossible to do this to an LX but I am wondering if it would work with my Ex. Thanks regardless.

The basic Aircon is a single zone unit, the full climate control unit is a Dual zone HVAC. That means the HVAC hardware is completely different IE. Independent Dual zone servo motors for air direction and mixing, sunlight sensor, cabin temp sensor, Data control of the rear demister, different wiring, two plugs from the HVAC Microprocessor controller back to the HVAC hardware.
