I was plugging in an AUX cable to the headphone jack, which worked fine. Upon hearing that I could get better wuality through the docking connector, I purchased one from EAS, but I dont think this connector works with the new iphone and ipod touch - I plug it into the dock connector, and then plug the other end into the AUX in my X5, and no sounds is fed to the Aux - it actually plays on the touch's internal speaker, as if it doesn't think it's plugged into anything.
