I should have been clearer. I had to pair the actual device to the phone with 2 different forms of BT - Edge 1000 and BLE_Edge. That's what the iPhone BT screen calls it. It took a few try's to get the BLE_Edge BT connection. Once you have the device and phone paired, GCM (Garmin Connect Mobile as note) than wants to sync with the device and uses the established BT connection(s) to do so.

In function, GCM will BT connect when you power up the device. It than allows functions such as Live Track and message and notifications push to the device (as desired, which is as I understand it, is the BTE_Edge BT connection). You can also as desired, see on GCM any Courses you've created in Garmin Connect and download that Course to the device for navigation purposes. If you track a ride, when you save the ride, it pushes the track to GCM, which then pushes to your Garmin Connect website account (if you create one), which can than push to RideWithGPS and Strava, etc.... The push of a saved track to Connect and onward can either be via a cell data connection from GCM (useful from remote start/finishes) or via a WiFi connection from GCM. In theory the 1000 can do WiFi direct, so no GCM required. I've never set that up on my 1000.
