Unfortunately, the 1031 has onofflap buttons mounted on bottom side edge rather than on the top face, so you need clearance between stembars and the bottom edge to hit the buttons. This has about 14 more clearance than any 1000 mount so lets you do that (barely). I found impossible to hit the buttons on a 1000 mount. I anticipate that it will be impossible to hit the buttons with full finger winter gloves even with this mount. Incredibly lousy button design by Garmin.
