    Hi Michael, I followed your instructions in regards to reformatting an Edge 500. Problem is that now Garmin Connect/Express, WebUpdater etc… wont recognize my device. I got through to step 23 and that’s as far as I can go now. Do you have any advice on getting my unit to communicate with Garmin. I will say that the device seems to be working but there seems to be less files/folders on the unit when viewing through Windows Explorer (i.e. it is recognized by the computer. Just not Garmin Connect/Express or the Garmin WebUpdater).
    I’m not sure that the file system looks that great either. There seems to be some strange looking folders and files that I don’t recognize (picture attached).

    At the very root of the device, there is only one folder (“Garmin”) and no files. From memory, there should be a number of files and folders. Under that Garmin folder, there is some odd looking files. I have attached a screen shot of these.

    It also seems to function in regards to activities. I can start/stop an activity and reset to a new activity so its all fine there but its critical to, at some point, be able to connect to Garmin and sync activities.

    Any suggestions on how to remedy this?


    • I think you’ve taken the right steps so far. What I mean is that up to this point, you’ve done exactly what I would have done.

      Do you have another cable? That.seeminglt silly suggestion sometimes.does correct the problem. More likely though, it’s a matter.of getting the software installed back on the device, and Garmin Express should be able to do that. Try.plugging it into a different USB port on the computer, then, in Garmin Express, go to devices. If the device is there, you will have the option to reinstall the system software.

    • I’m not 100% sure it will work on this device, but for more detailed instructions on the steps for using Garmin Express to reinstall system software, look here:
