Not sure about the Rino. What Mark is talking about is different than "off route recalculation". With the 60 and 76 series, when you transfer a route from Mapsource, only the waypoints and via points transfer. As soon as you select a route and hit "navigate" the GPS will calculate it's own route that hits your points. If you have enough points it will be what you intended 99.9%of the time.
Somehow the 276c and other units transfer exact routing info, keeping the route the same as you planned in Mapsource.
I originally thought this would be a problem with my 60Cx, but it's not a big deal in real world usage IMHO.
