I have a car stereo with a USB (actually mini USB) port, and would like to connect my iPOD to it. I have a cable (mini USB plug one end, female USB at the other) and an adaptor (male USB one end, 3.5mm jack at the other) which will allow me to do this, but I dont get music from my stereo when the iPOD is playing (the stereo says it is "reading" but there's no sound). How can i solve this problem? Is it because there is no power in this aux to USB connection? My stereo doesn't have a simple AUX hole or I would have connected through this (stereo is an Eonon 821).
