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) The FULL Make & Model Number of the device you are working with?
2) The AGE of the device?
3) When the update was done, did it appear to "go well"?
4) IF the update went well, did you turn the device ON - in golf mode - and see if the device could find and lock on the satellite signals?
Are you still relatively close to any course, and can power up the device again - to see if it will find and lock on the satellite signals?
Also, did you WATCH the update, and did it appear to "go well" - and include course updates?
OK - are you in an area where you have used the device before - SUCCESSFULLY?
OK - may I ask what program you are using to do the update?
And has this device EVER been updated before?
I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved?
I look forward to any further questions or results that you may have.
Thanks, ***** *****--. .-(im)
