You have to do them both, the zh_mcu.bin is an update to what you already have and preps the unit for the second part, which adds the steering wheel ipod controls and fixes a couple other functions.

Your Dynavin is set up for an external tuner, all V5s are. But since the US tuner isnt out yet, it isnt relevant to you.
