Hi: I want to install Sirius XM Satellite radio in my DB9. I am told that you should use an FM Modulator wired in for the best reception. I've seen the Youtube video on how to remove the radio but it didn't show the back connections. I want to order the FM Modulator so I have it in hand to install after I take out the centre stack, rather than tear it apart and then order the FM Modulator. Does anyone know (or have a picture) of the antenna connection at the back of the radio? Is it a standard antenna plug or will I need an adapter? Any other tips? Thanks!
