I have the same problems. Tried with SD removed but makes no difference.
Sometimes when I get a fix with external antenna and unplug it then, the
internal is able to hold the fix; but not always. Internal never gets a
fix on its own. 

I had the FR open once. I think the internal connector sits fast. I
haven't tried to unplug and replug it because the cable that runs from
the plug to the antenna scared me. At the point where it is soldered to
the antenna it is so thin and looked so fragile and worn off, I was
afraid it would fall off any second.

But I am not experienced enough to say whether this is normal.
