I've currently got the Stiletto 2. I would like to add Sirius to my 2 vehicles. I have a 2005 Chevy Silverado and a 2006 Chevy Impala. Now I would like to keep just one subscription, and not have to have one for each vehicle. The most obvious answer would be to get a car kit for each vehicle and just take my Stiletto with me wherever I go.

However, I would like to make it more "factory" like. I want to be able to change radio stations with my steering wheel buttons, ect. Basically I want my Stiletto to act as a Sirius tuner for my GM factory radio. Is this possible to do or am I stuck just having to go the car kit route?
