Agree with the majority of the posts here...jersey pocket in a plastic bag. Even if no threat of rain, the bag will protect it from sweat. If it's on your bars, you'll have the urge to look at it and take your eyes off the road. Even if you're using a nav app on the phone, those other apps will tempt you to open them. Keep in your pocket or saddle bag and out of the way until needed.
