What all cords do i need to install all of these. The manual has it running an xm box with a supplied xm data cable but i'm assuming that that is not needed with the surius box? i am just running the sirius box and the BTB200 and was wondering if i need to buy addition cables like another ip-bus cable.

Each one should come with an IPBus cable. You'll daisy chain them. One cable from the D3 to the Sirius and then one to the bluetooth module, or vice versa. Each one has an input and an output so you can chain them together. Just match the colors of the cables starting at the D3.

yup, there's diagrams in the owner's manual on how to connect multiple devices.
