I am sorry that you are having trouble adding your device to Express. This error most likely indicates that there is either a connection problem between Garmin Express and our servers or there is a device set up problem in our system.

To resolve server errors, please follow the instructions in the FAQ What should I do if I receive a server error while using Garmin Express?

If these steps do not solve the problem, I will need the serial number of the device so that I can check the device on our end.

Thank you very much, but it still doesn't. :(
Do you want the serial number ?

I sent you a PM.

The specified unit id is invalid

Hi

When I try to register my Garmin Edge 510 in Garmin Express, I've got this message : "Device Found Serial Number: The specified unit ID is invalid ".
And when I try to register the product on Garmin website, I enter the serial number but it says that the serial is invalid !

I'm very hopeless !! :(

Please can someone help me ?
