I haven't tried it yet, but for those of you (us) interested in uploading or downloading routes to our Garmins (mine is a 705), Garmin has a plugin now that works on Macs. For more info, check out Garmin's website, or do what I did which was to go to Google and ask - downloading routes to GPS, or some such. However, your best bet is the Garmin website.
Hmm. Let me say also, if the message is not clear that I've downloaded the plug-in.
