So I just got my new '06 scion xb (loving it BTW). I'm reading the manual and noticed the "AUX" jack by my parking brake. Manual says it's for hooking up an external audio device such as a cd player or MP3 player. Plug in a mini jack and you can use your mp3 player to play the sound via the xb's speakers. So I busted out the ipod and started it up but got nothing when I pluged it in. Anyone know how to work this "feature"? The manual has like 2 lines just saying to plug it in with a mini jack to the headphone out on the device but that's not working out for me.
