There really isn't many radio shops that can do the modification because of the fiber optic cable transmit the audio data to the amplifier. If you are in L.A. There is one shop I have seen that can do such modifications since the climate control is indicated with the ICM.
Replacing the ICM would require a software download to configure the new init to your vehicle.
