I was looking forward to having music controlable by the switches. So I researched out whic Ipods worked. I found a used 4th gen NANO and ordered it up. So I got music loaded on it today in about 5 playlists. I hooked up to bike, put it in "AUX" It does not show "Ipod" I can get the Ipod to play, but none of the functions work. Volume works but thats it. So do I have a bad cable? Or possibly a bum Ipod? I know the battery is bad as the unit will not work unless it is plugged in. So any ideas?
