So my Garmin 196 gave up the ghost and is not updatable anyway. So Im looking to replace it with one of the two above. One big question is (and I searched both manuals before asking this) do either of them give the current required glide ratio to a point? My 196 did and I had it on my custom field.. It was extremely helpful for final glides. Both of the units Im looking at have VNAV functions but cant tell if the have what Im looking for in the size the come in. Any one have experiance with either of these? Thanks

The Aera 660 can display glide ratio in a user-defined data box. It also has a vertical nav (VNAV) feature that is similar to a glide computer. All of this is explained in its manual:

I have seen the 660, and the display is quite bright in direct sunlight. A friend has one that he uses to display XM weather (needs the GDL-52 receiver).
