2) You do not have to change the bracket if you're converting from XM to Sirius. The Sirius tuner is smaller and will fit the XM bracket.
3) The yellow lead from the XM antenna is plug and play with the Sirius tuner. The data BUS connector is also plug and play.
4) You do not have to change the antenna or splitter when changing from XM to Sirius.
1) Signal with Siruis was horrible, even another member on another forum experienced the same number of cut outs. Reason why...see #3
2) You are correct, NO WORRIES for the guy getting the Sirius, but what happens to the guy getting the XM module, when it doesn't fit?
3)The BUS connectors are plug and play. The antenna leads are where the problem comes in...
Yellow is for a satellite signalGreen is for the terestrial signal.
See Satelittle radio doesn't always come form satellites. Depending on where you live and the number of obstructions, XM/SIRI has relays which help carry the signal on the ground.
XM antenna are split into yellow and green. You can plug the yellow only into the Siruis module yellow, but you will lose signal quality depending on where you live because you not using the relays.
Sirius antenna do not use the split signal. They carry both on one line. So the person with a Siruis antenna (yellow), pluging into the XM module yellow will not get a signal becasue XM requires both. They need splitter.
4) Correct again, but what about the other guy. They do not make a functional splitter that will convert the Sirius antenna yellow to green and yellow, therefor you not able to take advantage of both signals.
Eggy and I did this, and we had two major issues.
1) It was a great fit for me becasue all the XM suff fit the Sirius module and I did not have to change brackets.
2) My Sirius singal was lousy. It cut out under trees, underpasses, a cloud...something that my XM doesn't do. I get an XM signal in my garage.
Eggy did not get a signal at all because the XM receiver needed both leads, and he couldn't find a yellow to yellow/green splitter.
Basically it's not a fair trade for both parties.
