If I don't get the dealer installed sirius and but a small portable unit in the little cubby area this will block the aux. Do I have to give up this to put the unit there?. Thanks

 

I bought a "Y" connector, which plugs into the aux input, Sirius into one side of the Y, and a male to male mini cable into the other Y. I store the cable in the net on the right side of the transmission tunnel, and use it for my ipod.
