I've got it on my K1600 and I would NOT recommend it unless you have a way of mounting it closer than the dash. The sun makes it unreadable most of the time. There is a new Garmin model coming out that is supposed to be a lot easier to read when the sun is out.
I think this is a very subjective thing, based on your height and eyesight.
Taller guys (like me) don't have as much trouble with the glare....I rarely have trouble, unless the sun is right behind me (and I don't think anything works well in that situation).
Also, I love the location of the built-in mount on the 1600 out in front, so I don't have to change my eye level and focus to look at something closer. My eyes take a few seconds to adjust their focus back and forth, and I really like the mounting in the 1600 for this reason.
Your mileage will vary, as Dan's does. Having said all that, I've already gone on record as saying I'm up for the V. Dan, do you have a link or anything I can read about it?
