I purchased a Sony NAVU-83T, a Garmin 680, and a Garmin 780 to compare their features and routing capability. I kept the 780 and returned the others, but it was a very difficult decision.
The Sony unit [...] at Costco, and has a 4.8″ screen (1/2″ larger!). It has one of the best user interfaces on the market, primarily due to a few things: 1) you can always get back to the map by pressing one button, regardless of where you are, 2) you can always get to the main menu by pressing one button, regardless of where you are in the menus, 3) it has a split screen function that gives you lane guidance visually so that you know which lane to get into, well before the turn, 4) it has shortcuts, for instance to GO HOME you make a V shape on the screen and it takes you home…no menu navigation required!
