Hello, I have a GM Auxililary audio input for sale. I used this with my H3 to feed Sirius satelite radio to the stock radio it worked great. The part # is PXGM12. It has 2 inputs so you could use an Ipod and a portable Sat radio at the same time. It installs easy between the factory XM module and the headunit. I will include the original packaging and instructions. $40 shipped
