thanks for the insight..
if i read and understood right, u're saying the buttons constantly send signal to the head unit, but only the strengths of the signal changes when i press steering control buttons.. ?
anyways.. im not sure how that will affect my project since im not that familar with electric stuff..
BTW, here is a link that i found regarding ipod remotes..
http://www.maushammer.com/systems/ipod-remote/ipod-remote.html
should definately check it out if u're interested in what i'm interested in..
looks like of the 8 wires coming out of my zune remote, 3 are for audio left, right & ground, and one is for the power to the remote..
of the 4 wires left, one could be another ground for the remote (not the audio), and violla~! i only 3 wires left! forward, reverse, play/pause!
anyone more knowledgable than i.. ??
