'An Ai-NET head unit with an M-Bus changer is not compatibile. If you would like to connect an M-Bus head unit with an Ai-NET changer, it is possible with an Alpine adapter KCA-130B depending on the changer. The changers that will work with the KCA-130B (from a M-Bus head unit to an Ai-NET changer) are CHA-S604, CHA-S614 and CHA-S634."
