I got an iPod for Christmas, and I would like to use it to play music on the boat. I know I can use one of the FM transmitters, but I am looking for some sort of wired solution because I think it will improve the sound quality?My boat has a Pioneer DEH-P4600MP stereo with single cd player and radio. The front of the owner's manual describes it like this: "Multi-CD control high power cd/mp3/wma player with fm/am tuner." The book also says: "Using the Aux Source - An IP-BUS-RCA interconnector . . . lets you connect this unit to auxillary equipment featuring RCA output." Is there a way to create an iPod wired connection? Is the AUX feature what I need to use, or other? Is it worth it for the improvement in sound quality?Thanks!
