I had to figure out how to do the factory reset at the gym after I got the blue triangle of death when leaving work. Oddly enough it synced the gym plan I wanted and leaving it connected to the phone didn't seem to produce any other ill effects, but I stayed away from anything using GPS.
But yeah, the general advice for Garmins just now seems to be "just don't" and hope it doesn't triangle itself until the fix is out
Smells a bit Scandinavian to me. In Norwegian we also use "ur" that way, including "urspråk" (Ursprache, ur-language). We have a different word for origin (opphav), so ur remains a prefix that's difficult for us to translate.
Going by Wikipedia however, the English translation for Norwegian urspråk and German Ursprache is proto-language.
