RV660 vrs RV770
Looking at the comparisons between the 60 and the 770 it would seem that the new 770 isn't different enough to justify the extreme cost. Is there anything that makes it a major upgrade?

Compared to RV 660, the 770 has Wi-Fi for software and map updates, 6.95" screen vs 6.1" (note that the RV 760 has a 7" screen), 1024 x 600 pixels vs. 800 x 480. You give up the powered mount that the RV 760 had though.
