I don't know what software you were looking at, but I'm on a Mac and have no problems with my 705. But I've never been able to download a map from Google Maps to anything, or had much success creating maps on Google Maps when I didn't want their auto-routing option.
Are you looking for street maps (there is a freeware option, but I really haven't investigated it, because Garmin and Navteq have their copyrights for a reasonand I don't want to be out in the middle of nowhere with an untrustworthy map), or routing?
You can download a .gpx or a .crs directly from MapMyRide to your 705. I don't use courses at all (actually, people report fewer problems when they use courses, I just haven't bothered). To download your route, choose Route>Save to GPX>Download GPX, then choose folder Garmin>Garmin>GPX. Then when you're ready to navigate it, choose Menu>Where To?>Saved Rides, select the ride you named, and choose Navigate.
Make sure you have Auto-Recalculate set to Off or Prompted.
ETA: I haven't updated my maps yet (actually I'm waiting until next year, since there's been some major road realignment in my area that wouldn't be on this year's maps yet). I initially bought the bundled unit. But you have to actually buy the City Navigator disk to have integration with Training Center (if you use that). It's a little bit more involved, I believe, since I think you have to call Garmin for an unlock code once you've copied the maps from the disk to your chip - I'm 99% sure you can do that, but be warned that I haven't tried it. Still, City Navigator 2010 is available in DVD for Mac or directly on the micro-SD card.

I am riding primative roads and not paved city roads. I just updated my Garmin and there are no maps to update at this time according to Garmin's website. I don't have problems loading my ride info onto my Mac. I'm having problems with parts of Garmin's websites that are not available for Mac yet.
...followed by more whining about garmin.com website....followed by the perils of using a Mac to view some of their online stuff that wasn't Mac compatible. (I can't remember specifically the Garmin page but it didn't have to do with maps. I'll try and find it again.
