ooo yea i have a pioneer avic-d3 if that matters

im currently rewiring my whole system and noticed that the vss wire was not connected, my nav worked fine and everything was working but now that i have the deck out im thinking once i put it back in its not going to work right without the vss wire connnected.. seems like the alarm guy disconnected it idk, but now i have no idea which wire it is, i know when i installed it 2 yrs ago i connected it to a green wire, problem is alarm guy has some wire taps into green wires and theres more then one green wire.... any help???

has anyone tryed to downgrade the soft ware on the iPhone 3g so it will play videos on the d3 using the iPod interface cord?? Is this even poss??? I know people with the iPod classic are doing this to get the videos to work
