I am also having the same trouble as novellino21. I have a Sansa e260, and accessories for it aren't available yet. For now, I installed an Auxiliary Input Adapter to the back of my Kenwood and have a 6' RCA to 1/8 adapter attached to that. One idea I have is to put 2 RCA connectors somewhere in my center console. Then I'd have a short RCA to 1/8 that plugs into the connectors and to my mp3 player. But, I am not sure where a good place would be to place the RCA connectors. What are some other options? I saw a Mecury commercial this morning showing them using a Ipod. How do they do it?
