I'd like to add an additional aux input to my '06 model (with nav); it's fine if it is on the same path as the center console input, even if it functionally replaces it, but I need it to be in the dashboard area rather than in the console, as I don't want to run wires across and drill into the console. I'd be fine with it exiting somewhere around the power outlet at the bottom of the dash. Is the wire from the head unit to the center console accessible and identifiable? Thanks!
