OK I just purchased an 05 g35 coupe 6mt, and I'm looking to get aux in. I do not have a SAT button and I'm wondering how the pac-audio adapter will work. I heard someone on the forum discuss something about holding down the radio button to switch over to aux, but I'd like confirmation on this before I go and order one. Someone must be able to give me a straight answer...

 

you have to hook up the pac adapter before the aux input will appear on the stock radio. I just install it on my '05 G 35. works great!

 

It works....you don't have the sat button (rather RADIO), but all you have to do for an 05 is toggle the RADIO button untill you get to SAT 1.
