I believe the Sound Dock Box thats shown is a refurbished and NOT a new one ! It should come with all the electrical plugs in which i believe are only two plus the small plastic antenna . I purchased mine NEW. I doint feel secure with a refurbished prouduct ! F.Y.I. mine is working GREAT for me and is a Positive investment to me since I enjoy Music very Much ! Take Care and ENJOY
I took this from another website that lists what comes with a "new" one. I did purchase a new one and love it. SiriusXM Portable Speaker Dock Indoor/outdoor antenna Remote Radio adapters AC power supply Owner's manual Compatible with select SiriusXM Satellite Radios Including SiriusXM Lynx and Edge, XM Onyx, Xpress and XMp3 models, Sirius Sportster, Starmate and Stratus models. There are certain model that fit, others do not. Make sure your "radio" is one that will fit the adapters that come with.
