It look like the previous owner did the ipod modification to my car using a 3.5 or 2.5 jack that came out from the armrest box between driver and passanger seat. It is Radio Shack cable as the name is on the end of cable. How can i make that to work? Please if someone can point me in the right directions will b apreciate.

 

My car is a 2006 TL non Navi

 

Maybe he just wired it to the XM channel. try to turn on your XM, and plug in some tunes. if he retained the XM, there might be a relay somewhere. You would have to find the switch.
