Hello, I apologize for the lack of technical speak...I'll do my best to explain my situation clearly... For the past two years, I've had Sirius radio hardwired through my car (03 Infiniti G35). I'm not quite sure how the installers did it, but there's a magnetic antenna on the back of my car, and it's wired through the car stereo. All I need to do is hit the "SAT" button on my car radio and I'm listening to satellite radio. All the presets from the car stereo will work with Sirius and I'm very happy with that setup. Recently for my birthday, I received the Stiletto2. I also received the vehicle kit. Ideally, I'd like to listen to live satellite radio through either the hard wired car radio or the stiletto played through the speakers (so that I can save any songs/programming that I like while I'm listening). My first question would be if this is easily possible without running a second antenna from the back of my car up through the stereo (ie: can the stiletto piggy back off of the wiring for the Sirius that's played through the car stereo?). If the Stiletto can piggy back, how would I set it up? I assume I need to hook up the cigarette lighter adapter and then hook up the fm antenna (or cassette player option, which I'd probably go with). If it's that simple, would I be able to buy the cigarette lighter adapter by itself? If I don't need the antenna that comes with the vehicle kit, and I need to buy the cassette adapter separately anyways, it seems like a waste of $50 to keep the vehicle kit. Thanks.
