Anyone experiencing any issuing connecting via Bluetooth?
Someone in the VAHR forum reported such a problem. He said Garmin support told him, that there is an issues with bluetooth power safe.
After updating my company iPhone 5 to 10.0.2 astonishingly everything works as expected.
Those experiencing problem maybe should delete GCM and the device in iOS bluetooth settings. The reinstall GCM and make sure it is allowed to ALWAYS use GPS. The repair by initiating the pairing on the device and then start GCM. Now the device should show the pairing code.
I uninstalled GCM and erased the Bluetooth listing before reinstalling and it works fine now.
