I went running with my husbands new sony radio that straps on to the arm and the thing kept shutting off while I was running. He told me to make sure I put this little piece into the hold postion to keep it from shutting off. It didn't work. Do any of you guys know of some moderate to reasonably priced radios that strap on to the arm that actually work when your running, or can you let me know what you guys use? I need some advice so I can get something else. Thanks.
