Looking for part numbers for both belts. The main belt is easy to find, but I can't seem to find the smaller belt anywhere. And from the looks of it, the smaller belt needs to be cut off in order to replace the main belt.
The factory BT unit is not retained in my setup. All controls are passed through CANBUS.
Feel free to start a new thread with your particular setup/issues.
You bypass the stock Sirius unit, and use the aftermarket Sirius kit. The existing antenna is retained with a cheap adapter that plugs in behind the glovebox.

From another thread:
"For steering wheel controls -> Connect the KEY1 wire to Pin 10 (Red/Black) of the vehicle connector. Connect Pin 9 (Green/White) of the radio connector to chassis ground."
