Sorry to be the bearer of bad news, but the head unit for DSP with NAV systems puts out line out analog signals and the volume level is performed AT THE AMPLIFIER which receives its control signal from the head unit via the digital K - Bus. So, your choice is to either replace the head unit or have some type of multi-channel line out converter installed on the back end of the OEM amplifier.
