Hello @KH2052 ,
do you have any solution for your GPS problem?
I’ve figured out something similar. My GPS USB worked for several years, but I’m not 100 percent sure, when it didn’t work anymore.
In the meantime there are also some other topics here, which show some problems with GPS:
@guystewart @mpvader Do you know about these GPS problems and do you have any solution for it? Thanks.
