The Canadian Lancers don't come equipped with Sirius even with the S&S package (we also don't have the NAVI package).
As far as I looked into it you don't need to install no universal unit or anything like that to get Sirius working. All you need is a receiver and a subscription (obviously).
Say what?
Providing you get the 650w Rockford Fosgate system, the GT comes with a 6month subscription. I test drove an '09 GT last month in Vancouver and it definitely had Sirius.
Mitusubishi Canada also lists the nav package as an "accessory" in the GTS model for 2009.
