I gave my old Edge 305 to a friend (I have had a 705 for a couple years now), but he can't upload to Garmin Connect because it says the device is registered to my Garmin Connect acct. How do I "unregister" it, so he can use it with his account. I have searched throughout the settings for Garmin Connect, but can't find a reference anywhere.....
thanks !!
