Hacking the radio controls in your steering wheel

[Gabe Graham] sent us this step by step process of building a dock for his Zune and hacking is steering wheel controls to work with it. Like many of us, he was not happy with the performance of those little radio transmitters that hook to your mp3 player. He remedied the situation by mounting a dock for his Zune onto the console and patching into his stereo. The sound quality was great, but controlling it was a pain.
He had one button left on his steering wheel that was not needed for anything. He created a custom controller for the Zune that would issue different commands based on how long he held the button on the steering wheel. If the button was held for less than half a second, it would skip tracks, any longer and it would pause. Though he could possibly clean up the look of the LED sticking out of the console, the over all effect is quite well done.





awe-man… I was really hoping he had figured out and documented the protocol used to communicate directly to the zune port.
He could have just as easily polled the pins on the dock instead the IR transmitter.. it probably would have made for a much cleaner install (not to mention more useful to the Zune community) from the wired version of the remote I can tell you that there are dedicated pins specifically for remote functionality.
kudos for a zune hack though… MS got the portable media player right IMO, I only ever bought one because it was $80 on sale and I figured I could hack around with it, ended up liking it so much I just started using it and my ipod just collects dust.
