Well it's pretty simple. What I did was ground that wire somewhere else instead of the e-brake. My avic-n1 came with a little clamp that clamps into another wire so I clamped it into the ground wire, and it bypasses the e-brake thing.
I finished installing both the voice recognition and the rear-view cam. They both work great! I'm gonna take pictures now and post them on here in a little bit. I'm going to start a new thread, watch for it
