Auxiliary Won't Leave XM Radio
 

I just bought a 2005 Infiniti G35x and I was excited that there was already an auxiliary cord in the glove box and is wired into the dashboard. The only issue is that when I push the radio button I go from AM to FM to FM2 to AUX which changes to XM Channel 1 and then XM Channel 2 and then back to AM.

How do I get it to stop playing the imaginary XM radio and play my iPhone through the already installed aux cord?

I have a stock radio, with nav and no CAT button


The thumbnail below is what my dash looks like.


Thanks!
