My 02 Accord LX came with a AM/FM/CD Head Unit from the factory but did not come with the Steering Wheel Audio Controls. I recently upgraded to a Alpine UTE-62BT Digital Media Receiver and also upgraded the speakers. The Alpine owners manual states the unit is compatible with most factory steering wheel audio controls (adapter required). Would the wiring be in place in my LX's steering column to easily add the factory Steering Wheel Audio Controls or would it be a more complicated task? Also, what functions would the factory controls allow - volume up/down, radio tuning, etc.?
