I have a 2006 Single Disc stock HU with a stock Sirius tuner. I've been looking for but haven't yet seen a posting of the input connectors on the stock '06 HU. I know that there is a CD changer port on the HU, but is it taken up by the AUX port in the center armrest compartment? Also I have no idea which connector the Sirius plugs into. This leads to a few questions/requests:

1. Can anyone point me to pics of the back of an '06 TC stock single disc HU (or list the input connectors)?

2. Can anyone tell me what port the Sirius tuner plugs into on the radio?

3. Is the CD changer port on the 06 HU occupied by the center armrest compartment AUX port?

Basically, I am looking at connecting a PIE TOYO to Alpine CD changer adapter to the AUX port with a PIE TOYO 12-pin "Y" Harness to accomodate both the steering wheel controls and CD changer. But I need to know if that AUX port is available (especially if a stock Sirius tuner is in the configuration). I wanted to ask because I'm a bit reluctant to pull apart my center console just to check all of the connections. Thanks!
