The touch screen on my Edge 830 is much too sensitive. If I ride indoors with it on my handlebars it gets triggered by sweat, if I ride outdoors with the slightest bit of rain it gets triggered by that. I got caught in a rainstorm a while ago and the thing just went totally wild, right at the moment when having a working navigational device would have been most useful. Before I bought it I heard that it had multiple sensitivity settings, but I can't find how to change them anywhere. Does anyone know?
