KB112 said:Our trucks have a hook up for a factory sirius tuner/antenna. If you want XM you need to use either an FM modulator for sound or a buy this special aux input adapter. It lets you hook up outside sources to your factory deck to playback through it. I have the infinity setup with single disc/cassete, I dont see why the 6 disc version won't use sirius as well. You should have a mode button on the deck.
That allows you to switch between am/fm/cd and your aux source. For the latter question, the answer is no. There are no aftermarket decks that hook up directly to the factory steering wheel controls. You need another adapter for that as well. But its faily affordable at $70 or so and lets you retain the use fo your steering wheel controls.
