I did a quicky test. Forced close the Garmin app on an iPhone. Booted the 1030. Watched as the 1st 1030 BT was made but not the 2nd. Waited a bit, no 2nd connection. Turned off the 1030, turned On the GCM app, powered up the 1030 and watched as both BT connections were made. I mean, it seems obvious in retrospect to have the app running.
