I think you have to install the GPS "module" separtely, from the Autoroute CD - it's not installed by default, which may be why yours is "greyed out".
Not sure where you're going but there ain't much on Autoroute outside Europe. I have Autoroute and MapSource, but my favourite by far is Memory-Map, which uses "raster" (real) rather than vector maps. Very easy to import/export routes, waypoints, tracks, and you can get a very good deal with half UK coverage of genuine OS 1:50,000 maps. You can also import/scan in and calibrate your own maps, as I've done with part of the Michelin 953. Look at www.memory-map.co.uk.
You even get a 3D terrain model included with the 1:50,000 maps - it's amazing! Also available are satellite photos of UK (12 regions cover the country?)
BTW, you can import "points" into Autoroute from an Excel file. Go to File/Import Data. It's a bit basic though! You can't import routes or tracks.
Here's Morocco on Autoroute:
and Memory-Map (953 scan):
Note that neither are fully zoomed! You'll notice more detail on the 953 than on the paper version.
