D2523T Can't get fix

Hello,

I’ve been using the D2523T for a few months now and usually it gets a fix within a minute or two, but for the last several days it can’t get a fix at all. In u-center it shows no satellites in view and all the output is simply blank and looks something like:

$GPLL,99,99,99

I usually have it next to a window and that has worked fine up til now, I also tried taking it outside for about 10 minutes and that didn’t make any difference. I’ve tried to do offline assist by doing a flash update in u-center but that gives me an error saying “No acknowledge received” and fails.

Anyone have any suggestions?

Thanks
