Pouch fit my Garmin 52lm perfectly. The revision I had to make is in the back for the charging cord. Cut a small rectangular hole and fits perfectly. One area you have to be careful is on the bolt that holds the strap. If you put it on without any protection it will scratch your powder coating on your handlebars. My fix was to add two washers on the inside of the pouch. I also super glued a piece of material to cover the screw that protruded through the pouch so when you stretch the strap around it the bolt would not to scratch your handlebars.
