[quote name="PaisanNYC"]you can definitely hook the parking break ground wire to a switch. The ground wire into the harness is a bypass for the AVIC-Z1, not the N3. Just remember that after grounding the parking brake wire, you have to peel back the "void" foil label on the headunit and flip the small switch under it. (Peeling back the label voids your warranty with Pioneer)[/quote]
Great, exactly the post I was hoping for!
Thanks alot for your help, I'll be doing this tomorrow night!
