It sounds like you might be experiencing some hardware issues if the computer does not recognize the FR10 consistently when it is connected. The FR10 is a mass storage device so the computer should recognize it as a USB Mass Storage device every time it is connected. Please see the FAQ: Why doesn&#39;t my computer detect my device when it&#39;s in USB Mass Storage Mode? <br /> <br />Make sure Garmin Express is up to date and delete the FR10 from Express and Connect then pair it again. <br /> <br />How do I update Garmin Express? <br /> <br />How do I delete a fitness device from Garmin Express? <br /> <br />Let us know if you have any other questions or contact Garmin Product Support by phone. <br />Curt<div style="clear:both;"></div>
