YES.  On startup it should first attempt to read from a live GPS on the GPS 
port, for a current position, instead of regurgitating a cached one that could 
be hours or days old.    What's weird about this bug is that the GPS indicator 
is flashing, indicating that the radio has detected a live GPS, even as it is 
sending obsolete, cached data.
