[QUOTE="Gypsy3000, post: 8694181, member: 678753"] I appreciate the reply, however my objective is to wire the hu for ignition-off use. Are you saying that if I follow Pioneer's supplied installation guide and wire the hu's yellow main power-supply directly to the fused battery-feed but the red "signal" wire to a supply that is strictly ignition-on that I should still be able to switch-on the hu with the ignition-off? How? I've tried various methods, holding different buttons for varying lengths, etc, but nothing will activate the hu with the ignition-off. Conversely, as soon as I key-on the ignition the hu activates normally. Is there a Trick? Is there some internal circuitry in these later pioneers that disallow ignition-off use??? Again, could potentially-lowered battery voltage be a factor? Thanks for your time! [/QUOTE]
