Yes, I order a wiring harness cable and installed.. I also upgrade my speakers from non-DSP to DSP speakers.. Does the lady's voice come from the 6 1/2 speakers in the front door? I have navigation sound, but no voice module sound..Humm I think the DSP speaker in from door only have to wires and not four like the non-DSP speakers and I cut the other two not going to the DSP speakers..
