IPOD HOOK-UP

Again, i know this has been beat to death, i am trying to hook up my IPOD to the MP3 jack so i can have some quality tunes and no CD skipping. I bought a male to male cable. One side going to the IPOD head phone jack and the other going to the MP3 jack, then switched it to AUX but i got nothing. What am i doing wrong??? I have the stock Sony Explode deck in my 05 VLX. Help...PLease...
