The output audio is 3.5mm located in the console. Connect one end of the cable to the headphone jack on the ipod and the other end to the output audio 3.5mm in the console.
IF you have the car adapter you can plug it in the cigarette lighter jack inside the console too.
You will need to switch the audio option from CD or radio to "aux".
Hope this isn't a dumb question....I have an iPhone but it is a pain in the butt to put it in the console & connect it (for music) when I make several short trips. After each stop, I have to remove the phone and take it with me. So, I ordered an iPod Nano. Will I be able to use the same cable I now use for the iPhone, to charge the iPod and the other cable to play the music?
I'm disappointed with the FM reception in the ES, so I'm resorting to my own music. I miss XM that I had in my old vehicle (TL), but I hear XM/Sirus is going belly up (in about a year), so I don't want to invest in an XM radio.
