Forerunner 305, Windows 10, Garmin Express - No maps, no elevation after synch

Former Member

I've gone through all the steps of updating drivers, forcing the USB drivers, disabling all other running apps, etc...

My Forerunner 305 will no longer upload maps or elevation profiles. I use it for mountain biking and all I get now is speed, distance and heart rate. What I care about is the elevation profiles and maps and they absolutely will not upload.

I've done a full master reset and if I walk around my house a bit I can get a map to show up once in a while, but every time I think I have it working I use it for a ride and when I get back I get a big fat nothing.

Also more often than not I get a Device cannot start (Code 10) and I have to continuously disable/enable and disconnect/connect the device until it finally starts. I've tried it on 3 computers with more or less the same results.

Someone please tell me this is able to be resolved?

    When you say there are no maps and elevation, are you referring to viewing activities in Garmin Connect? If so, then your question with regards to that functionality should be posted in the Garmin Connect or Forerunner 305 Forums:

    AS for the Error code 10, this is a Windows Device Manager error code. I found some troubleshooting information on Microsoft's website on this error here: https://support.microsoft.com/en-us/kb/943104

    Garmin did release an updated USB Driver on 4/15/2015, version 2.3.1.1. Try the troubleshooting in our FAQ:

    How do I resolve the "USB Device Not Recognized" error when connecting my Forerunner 205 or 305 to my computer?

    If you are still experiencing difficulties after trying the drivers, port, cable, and another computer, it may be that the device or the cradle is malfunctioning. I have connected a Forerunner 305 successfully to multiple Win 10 computers here with no issues.

    You may also want to try cleaning the contacts on the cradle and the device: How do I clean the contacts for my rechargeable wrist-worn device?

    Contact Product Support by phone if you continue to have connectivity issues.
