I've downloaded the Garmin Express. I was able to link my Garmin Edge 500 no problem to Garmin Express but when I try to link my Garmin 910xt it reads 'specified unit id is invalid'. Any ideas on what I can do to sort this out.
I am sorry you are getting a message that the Unit ID is not valid. I have sent you a message to submit the Garmin Express logs to us. Once the logs are submitted, we can examine your error more thoroughly. Please let us know once they are submitted.
We appreciate your patience in resolving this issue.
