Hi there and welcome
On the other computer, could it be detected on that?
Can you please Remove the charger from the unit and hold the power button to off for 60 seconds.
Release, then connect it to the computer, turn it on and tell me if it is now recognized please.
Let me know the results please
ok, it does not show up in Internet Explorer, like new ones do.
You need to use Garmin Express which you can get here
You connect and interact with it via this.
Can you try on a different computer and tell me if it is detected on this please?
ok, can you connect using a different cable and tell me if it is then recognized please.
ok, but the GPS is now not working on multiple computers correct?
We will need to attempt to reset the unit to rule out the firmware as the issue.
This will remove all data then return the device to new.
To do this, please do the following
1. Hold down the MENU + ENTER button at the same time 2. tap the POWER button3. HOLD MENU + ENTER until you see the dialog on the screen4. Select yes or no
Complete the setup and then connect it to the computer and tell me please if it is then detected.
are you able to do it like this?
Thanks, ***** ***** the issue
It is the internal mainboard that has faulted, we have ruled everything else out
I am really sorry about this and you are going to have to return the unit to have it replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you.
