On my iPhone, in Garmin Connect, I have 3 devices under the "Registered to in Garmin Connect" (friends GPS' which I had repaired) and I cannot find anywhere to delete them. I logged into my Garmin account (https://my.garmin.com/mygarmin/customers/myUnits.htm) but those devices are not there. They don't appear on my homepage in Garmin Connect (web). I shutdown Garmin Connect for iOS and restarted it. The devices are always there.
How do i delete them ???
