Yeah. There were a lot of folks that updated in early January that encountered these problems. A newer update was issued near the end of January, and I haven't heard many problems since then.
Almost no one had much luck in resolving.
The white box on-screen about GPS issues is so common it is probably normal, except it should go away within a few seconds if you are outside. If you are inside, it may never go away.
You can try to do the update again. If it shows everything as up to date, that won't work.
There is also a way to bypass the UpDatePilot and do the entire update with SD cards. We can talk about that if doing the update again does not help.
