Hello & Welcome to Just Answer,
Sorry to hear of any issue you are having with your device.
To help you with this issue, may I ask:
1) What was the "condition" of the device BEFORE connecting to the computer (working well, fully charged, etc.)?
2) Does the computer "see" the device - before Garmin Express is started?
3) What is showing on the display OF THE DEVICE - when it is connected to the computer?
Please use the REPLY box below.NOTE: If you see ANY requests for "additional services" - such as a phone call - please understand that these are sent BY THE SITE AUTOMATICALLY (and not me), and I may NOT be available by phone at the moment of that request. Feel free to DECLINE (close) any such offers, and continue in this text/chat form.
