My VistaC has had this problem. The glue came unstuck while the unit was on the car dashboard in hawaii. I did as has been suggested earlier and took the rubber off, cleaned all the glue off (I couldn't find a proper solvent, and think that I might have used vodka , but it came off ok!), and glued it back with superglue. It's not ideal, as the rubber had stretched (possibly this is the root of the problem), and so I couldn't get it on tightly. It still seems to be waterproof, (though I've never tested that 1m of water for a minute claim, so can't tell you if's as good). I know a fellow cacher who's B&W vista did this, and he kicked up such a fuss that garmin sent him a shiny new vistaC (when they were new and shiny). Good luck with it.
