My 230 has Sirus, etc.
nd by that answer, it sound like a retrofit of the Boston Accoustics set up (or at the minimum the related amplifier) is plug and play to my existing head unit. Curious as I have no amplifier at all by the spare tire. I guess once I open everything dealing with that will jump out at me.
Related, is there somewhere I can download wiring schematics for my Compass so I can preview the wiring differences between the various set ups? I'm big on leveraging into what the factory already put there for any retrofit projects.
