We went with the GARMIN RV760 LMT. One reason we went with the older one over the 770 was the fact that all the hookups are in the base so you just have to push a button and lift off the unit.
We also connected the backup/side cameras in our VEGAS to the 760, giving us a much better monitor than the AXXERA. And the GPS is right in my normal view, without having to look down and to the right to the radio screen. The GPS also has the "judging" lines on backup so it is much easier to judge distance.
Oh yeah, and the GPS works good, too....
