Do all 05s have the SDARS (Sirius) connections in the back?




The receiver needs to be the same flavor as your head unit. For a 2005 MY car it should be MOST. The fiber optics forms a ring with other options connected to your audio gateway. You must install the receiver in the proper place and order of the ring. The head unit will need to have a chat with a STAR computer to "version code" the head unit to recognize the Sirius receiver.
The factory calls for you to drill a 20mm hole in the center of the trunk lid. The cables from the wheel arch area finish under the trunk lid lining for the antenna connections.
For people that don't feel like a hole in the trunk lid, you can mount the antenna on the package shelf, or below the grill on the hood near the windshield. You are on your own to get antenna cables long enough. There are newer antennas that are a tad smaller and have only one cable. There is a Y cable to connect a single cable into the two jacks on the receiver. One jack is for signals from space, the other is for signals from ground repeaters.
The 05 receivers spent a lot of time finding the sat signal. You could drive miles before you heard a sound. Sirius promised help, but never delivered. Sirius accounting and telephone support is also a study in frustration. I turned off my receiver, and sling the signal from my home receiver to my EVO for free.

Do you happen to know if 203 545 11 40 is the correct part number for the SDARS bracket? The only number I can find on herer is a B number that doesn't appear to be good any more.

I couldn't quite figure out the final configuration on passenger side of the tranny but basically it had to be connected at that point to the fiber loop/daisy chain. one component must be looped to another and so-on. The dealer then has to use STAR to version code it to you car. I had the dealer make the connection in the tranny hump arrea, and version code with Star. After that point I then had a soft button under radio that now says SAT. It was blank prior to that. They charged ~$125 to do this work.

PM sent.

I do have one more question, what did you use for an antenna? Did you go aftermarket or did you use a factory antenna? The only aftermarket antenna I can find that uses the same blue connector is a GPS antenna, will that work?
Tell ya what, i will take some pics for you in the next day or so. I also ordered a new roof mount antenna and will take pics and write up a DIY as i re-do it.



Installed SIRIUS last night (sans antenna...I'm working on a few "options"...although I have the OEM antenna...I am in the camp of NOT drilling thru and disrupting the visual of my trunk...)
Here are a few NOTES and pictures if it can help anyone...
Antenna frequency range of 2320.0-2332.5 MHz DARS for SiriusXM
@4:10 FIBER Connections
