The MZ-1 and MZ-3 send data to only one app at a time. To ensure that your data uploads properly, you should not use the Myzone app and MapMyRun app simultaneously. For that reason, we do not recommend using the MZ1 with MapMyRun. To upload your MZ-3 at the end of your workout, close MapMyRun then upload your workout to the Myzone app.
Step 1: Put on your Myzone belt and listen for the beep to make sure it activated.
Step 2: Open the MapMyRun app and on the 'record' screen, click the three dots found in the bottom right corner of the screen.
Step 3: Click on Apps & Devices.
Step 4: Scroll down under Workout Devices and select Heart Rate.
Step 5: Select Auto-connect and click on Connect.
