This is my experience.
I have been using the Streak's internal GPS. With xcs version 6.4 I noticed
on multiple cases, mid-flight, the screen and infoboxes will freeze while
the touch screen is still responsive. So I could bring up the menu, Quit
and restart. After a short while, it would happen again. Then XCS will say
it is now waiting for a GPS fix. I quit again and start an app for checking
the GPS status. And indeed, the Streak is unable to get a fix. Weird. All
this during flight. And would stay that way for at least an hour, but also
even until the end of the flight.
So I got another brand new Streak from EBay, and the first time I flew with
it, same exact thing! During the flight I pulled out my first Streak,
started it and it was fine! So at the same time one is working (the fresh
but older one) while the other (the new) is unable to get a fix for the
remainder of the flight.
Up until now I had suspected that the on-board GPS of the Streak is a
marginal design. And XCS is not recognizing this particular anomalous
situation when it initially happens, so it freezes. I did notice from the
beginning that the time to get a fix with the Streak is unusually long, so
I suspected the chip-set is not state-of the-art.
But after reading the comments here, it may be that it is a f/w issue on
the Streak. Don't know.
For the next season my plan is to use my new PowerFlarm as the GPS source
for the Streak via BT. I still like the Streak a lot and would still
recommend it, with this caveat though. At least until we have reliable
work-around.
