I dont think so. I've bought three different radios over the last few years and tried to listen to them through my Autocom. Both the FM and DAB ones rely on a specific, custom headphone cable to provide the antenna. A standard, jack to jack Autocom style lead doesnt provide enough reception, and so the quality is pretty low, and frequently loses its signal.
If you were in America, you would be able to use the XM radio service, but I dont believe that will ever come to Europe.
One thing I didnt get round to trying was to use a jack doubler or splitter like this:
And running both the supplied headphone cable as well as the Autocom connector.
Might be worth a shot; they're only a few quid...
