And I have sort of eluded to this already...
Garmin is ACE at making units that are "intuitive"... If you can navigate the features on any Garmin... You can walk up to any other Garmin unit and figure out the basics in mere seconds...
From the e-trek to the big bad interfaced units on big boats...
Some makes I cringe to see on the helm...
Before i walked up to my first DeLorme I thought it coundn't get worse than a Magellan
Furuno units were just a bit more user friendly than the Magellans...
