The only thing that I personally can do, would be to print the map and then copy the print on a scanner and save as a .jpeg image. Insert this .jpeg raster image into your ACAD file. Make sure that a distance or barscale is incorporated with the .jpeg image so that you can scale the image when it is incorporated in ACAD.
I would probably 'alt'-'Print Screen' the window into the clipboard, paste it into Windows Paint, then rectangle around the portion of the map that I want and copy it into a new Paint file. I'd then save it as a jpeg image and insert that into the ACAD file.
In Firefox, you can add download extensions to "grab" the map images. The only issue is that the maps are divided into sectors and are not one complete image. You will have to piece them together.
