It seems that in the place where you are the device do not see any 
satellites. This near always happens indoors and is frequent inside many 
trains or other vehicles. Just go into more open place and wait for 
several minutes. In the heavy rain the device may not see the satellites 
anyway - then try when the weather moderates.
