While it's well and good that I get a temporary lock, it is just that and does not carry over to navigation software to be of any meaningful use. For me, gps is unusable. It is far to inconsistent. I have made a myriad of adjustments over time in the past year and had high hopes transitioning through os upgrades, but there is really no usable gps, at least not for any length of time greater than a few minutes.
