Hmmm. I don't get these phone connection problems with my 530. In general, I've heard that *if* you have the choice between an ANT+ device/connection and a BT device/connection, Garmins seem to work better with ANT+. I have a power meter and HR belt that use ANT+, so my only BT connection is my phone (which I keep in my pocket in the middle of my back). Maybe that's why I've been lucky. But I'm not about to run out and buy a BT power meter and BT HR belt and BT speed/cadence sensor just so I can check.
