A couple of days ago, I posted a story about several new Garmin eTrex GPS units due this fall. At that point, the Canadian PDF catalog page was not available online, but it's back now and the full story can be told.
The big news isn't the high-sensitivity chipset, it's this blurb from the ad...
Also “GALILEO” (the new navigation system under development in Europe) ready as a future path that will accommodate a drop–in chip when available in the future.
That's pretty exciting except for the fact that Galileo literally can't get off the ground. According to what I've been able to find, only one of 30 satellites has been successfully launched. So Galileo compatibility, while it does show Garmin adding a (potential) new feature to its handhelds, is hardly a good reason to buy one of the new eTrex units.
