I have a panasonic sirius receiver, and I am planning on getting a panasonic sirius ready headunit. Now my question is, how does the receiver plug into the headunit? I know it plugs into the cd-changer input, but is that just to control the stations? Does it use the aux inputs? I want to add a dvd player later on, and I dont want my aux inputs taken up.
