Buggy after iOS 6 – Bluetooth GPS Status Tool Review
This is the only app that can always read the device. After the iOS 6 upgrade apps won't connect reliably to the Dual unit. One app displays "Poor signal" and another won't display an error or work. I suspect the communication errors are iOS errors possibly outside the control of developers. But what is odd is that this app sees the GPS and reports a location but apps trying to read it cannot. Or at least cannot reliably read the device.
