I have a complete Bose 3-2-1 GS Series II system that was used for only a few months. It was originally purchased at Best Buy. Unfortunately, I haven't used it in quite some time. All manuals, cords, etc. included and it is in as new condition and was boxed and stored when not in use. Guaranteed working and in mint shape.
I believe the DVD player is also region free but I can confirm if it is of interest to a forum member.
