wait, u have a 2007 and u can change music from the steering wheel, with a AUX connection??
OMFG, tell me how
i have my itouch plugged in most of the time and can only control the volume, but i can not change tracks with the steering wheel, i have to use the itouch to change the song
i also have a Cowon S9 that i use sometimes and its the same story as the itouch
also tried my phone (N97 Mini), same story, and a iStation T9, same story
also tried a N95 8gb aswell, same story again
if your talking bout AUX, you can plug anything in
on the newer models with the USB, i dunno bout that, but im pretty sure all 2007 only come with AUX
