I gave you info on what to do.

To perform a prompted User Data Clear on the Edge 1000:

Power device on
Touch Setup menu (tools icon)
Select System
Scroll down to select Device Reset
Select Factory Reset
Select check mark (right) when prompted to Reset all user settings?

Clearing the user data will restore all of the device settings to the factory default values.


Then connect with Garmin Express and do any update that it shows.
