I just purchased a Dual XGPS170. My wife is contemplating purchasing a Ipad Mini2. It comes with iOS 8.3. I'm told by the Dual folks that iOS 8.3 has Bluetooth issues. I'm also being told that iOS 8.4, due to release by 30-June, solves this.
Both of the above comes from Internet research as well as emails from Dual and speaking with Apple...
So, not sure if it's an Ifly or Dual thing. I think it may be an Apple thing. Oh and the Ifly product has some very nice features. I have shown it to folks running other products and have sold them easily...
But, I do hope iOS 8.4 fixes the Bluetooth thing since I'd like to steal the wifes Ipad, once she gets it.
