Which Garmin, if any.

Here is a page I found through Google when I was having similar problems ages ago. I think I did the ticking boxes thing with the drivers and it started working again.

Thanks very much. I can't do any more until the Garmin site is running again (down since yesterday). Meanwhile I found yet another amazingly helpful article by Rainmaker
