If you thought it was an internet or NOAA thing that would straighten itself out, apparently not. Even units that still have the display now will lose it on the next reboot if not updated to new software.
Are you talking about the Beta release software upgrade for that covers a bunch of feature improvements s including Temperature Display Compatibility
To maximize compatibility with the National Weather Service, DSX concurrently tries to obtain the local temperature from the internet using both the old method available in 3.41 and earlier and a new method introduced in version 3.42. If the local temperature is not available using the new method, DSX will fall back and try to obtain the temperature using the old method. ??
Fast and easy if you have remote access.
