No, the Audio Cable from the Maestro goes to the 3.5mm AUX input jack on the Pioneer H/U for wired remote inputs, oddly enough. The AUX cable from the SU2 harness is the center console jack, and since the 3.5mm AUX input on the Pioneer is used by the Maestro, you have to get a 3.5mm headphone jack to RCA adapter and plug it into the A/V input on the Pioneer to retain the port in the center console. The 3.5mm wired remote input on the Pioneer is unused.
