Sportster 4 Sirius Radio in 2003 H2

[Skulz]

Not sure if anyone has had any experience with this yet as the unit is fairly new.
I want to get the plug & play Sportster 4 Sirius radio and install it in my 2003 H2 that does not have satellite radio currently.
Rather than use the FM frequency to synch the two radios, I'd like to hook the S4 directly via wired connection (or find some chain that does this).
Are there any other issues I could experience?

Any help is appreciated.
Thanks in advance.
Cheers,
