RE: iPod help
Easy, best quality, way on the cheap is a cassette adapter(if you have cassette). Next would be a fm adapter to send your signal to a predefined fm frequency. Do consider a quality unit if you go that route, cheap units will not sound as good as the cheaper cassette adapter. Best option is a direct fm modulater attachement. It plugs directly into your head unit's antenna jack (or,in some cases, attach directly to speaker wires).
