As of today my girlfriend bought an Edge 830. I already had an 830. I thought it would be easy sharing courses using the device transfer option. After being able to transfer one course to the new device, transferring another course isn't possible anymore. We use the described method for pairing both devices. The receiving device lists the Edge 830. But after selecting the course name on the receiving device and press the confirmation arrow, almost immediately the receiving device gives the error message 'transfer failed. try again'.
Both deviced run on software version 8.10.
I don't seem to find anything inline on this problem. Any help would be appreciated.
