Thanks, but i don't think the Glo stream replaces the internal GPS on ios7 when the Glo attached, because the gps sensor only show "iPhone GPS connected @1Hz", but the Glo do works well with ios6 at least 3-4Hz.

Could you please check with that?

Thanks!

Garmin Glo can work with my ios6 iPhone but just at 3-4hz mode.

When i update my iphone to ios7, Glo can connect to iphone with bluetooth but never show on the laptimer's sensor list again.

please help, thanks.
