If you have concerns about cellular coverage a 372 is probably worth it for the xfill feature alone. The correction format is less of an issue than it may have been in the past with many cors operators providing multiple output streams but you would have to check to be sure. Last I knew nav2 and 3 were basically the same. The nav2 design was updated because the hardware to build them wound no longer be available. The two function the same but the internals are quite a bit different so it got called a nav3 rather than calling it a new revision.
