Hello Philip and thanks so much for your message. Sorry I didn't see it sooner. I don't have satellite radio, or at least I'm not paying for anything like that, but I will try to lock the car every time I leave it in the garage and see if that has any effect. It's sure to keep the chipmunks out, at least, right? I had that problem last summer when they came in and chewed all the wiring under the hood! Now I keep Altoids handy and sprinkle them into the engine from time to time. My younger brother had an old saying "If it ain't one thing....."
