I am wondering if there is a fm plug under the stock antenna or if the plug is only found behind the head unit in a 2006. Installing a direct fm sirius adapter and don't really want to tear the dash apart if I can avoid it but I don't want to tear into the rear panels and find out there isn't a plug below the antenna either.

 

i dont know about a 2006, but on a 2003 i think theres a antenna amp under that side panel near the antenna mast. im sure its the same with 2006. But there is a fm wire that you can plug into. Otherwise i would just take the dash apart. It really isnt that hard, unless you have 50 pounds worth of wire back there like me

 

thanks, I think I'll try pulling the back panels first to see and if that doesn't work out i'll tear into the dash
