Yea I had this question a while back, and was referred to ^^that link, looked like too much work so I got a radio that has an ipod interface, so it charges it while giving me the function to control the radio/ipod at same time. also it was a single din radio so I got the pocket to go with it, its VERY useful!
Thanks fella! That's a pretty clever idea. I think i'm going to try it. Also he said to refer to a diagram in an earlier thread to know which wire to solder to which terminal, anyone have a link to that thread or diagram?
