Not sure if I am missing something here but I never get position lock on my Movi Pro. I have had it sat in an open field with excellent all round visibiliit of the sky and left it standing there for 1/2 hour and not had lock even with 10 odd satellites detected. Any ideas? What I have done on another Movi pro is take out the rather crap and cheap GPS antenna (the top one) and replace it with a helical antenna. The satellite pick up is a/ much, much quicker and I get more satellites but still no position lock. Hmmmmm
