agreed.. xm and sirius are effectively the same other than the sports and talk. for music it's the same. I love my factory sirius.

 

Just bought adapter on ebay for factory antenna to hook up fm modulator for xm and sirius.cost is about 10 dollars.look under car audio

 

I was really just joking....I have had Sirius since 2003. We just got the wife a new car that has XM in it and for some reason she thinks the music on Sirius is better...I don't know because I am an Sirius listener. It has what I wants to listen so I am happy.

XM/Sirius/or regular radio as long as you are happy with what you are listening too...I just like to poke....

 

XM and Sirius merged.. some XM radios have some SIRIUS channels now... Not sure about the other way (although talks say that SIRIUS users are making out with more XM channels on SIRIUS than the other way)...

You may need to update your radio/device to get the new channels (software request via the internet)...

I had the ROADY XT up until a month ago (cancelled it, but may go back)... started seeing shifts in channels, and updates... now I am still using XM online and see a few SIRIUS channels on my XM login. This merger has been in the works for like 2 years.

Hope this helps clear up the channel and which one, mystery. As for hooking up... Best if you can wire into your antenna directly, or better, via RCA (which I KNOW is what he was asking)... BEST would be radio with XM already in it.
