Did you try what I described above? Perhaps I was not clear that the "Raster Product" is something defined by ArcGIS to summarize the entire satellite scene. If you will read our help to understand what the Raster Product is, and then open ArcCatalog and find the Raster Product icon (looks like a raster with satellite on top of it), you can expand the Raster Product (+ sign) to find "multispectral" inside, and drag that into the map.
Either that, or as noted in my original post, learn how to create a mosaic dataset and add the Geoeye scene into it using the GeoEye raster type, then add the mosaic dataset into the map.
Note if you are not finding these options please let us know what version of ArcGIS you are using. I am assuming you have 10.3 or later? If you are using a much older version my advice may not be appropriate
