I have a 99 328i, no NAV, no iPod Adapter option, and only the single CD player in the dash. All I have is the standard Aux Input jack in the center console. On my dealer's advice, I bought a 3.5mm stereo audio cable at Radio Shack and plugged it in, essentially treating the car like a pair of headphones. Music plays but it's very poor quality, like listening to AM radio. BMW suggested using a shielded cable (I don't know if those exist for a 3.5mm cable). Can someone tell me my options? Ideally, I'd also like to charge the iPod while it plays. Please don't suggest the FM transmitter option. I'm looking for something better, although it does sound better than what I have now with the hard wire connection.
