i drove around in my friends car for a couple of days and i gotta say, XM Radio rules.. a lot of content all the time.. so i'm really thinking about getting it..
the only thing is that i'm not sure what's needed for it

i have KDC-X969 HU.. on it says that it's "Sirius Enabled" but doesnt say anything about XM.. i also found this
