I tried to connect SKYLAB SKM53 GPS Module with my Arduino UNO , and i followed the instructions in this link
http://competefornothing.com/skm53/
but my result shown like this..
Latitude : 0.0000000 :: Longitude : 0.0000000
Latitude : 0.0000000 :: Longitude : 0.0000000
Latitude : 0.0000000 :: Longitude : 0.0000000
I tried to connect the gps with external supply but still not working.
I need to know what is the problem? I tried with another code but it still not working.
I need help here..
My code with connections
My code with connections shown at the first of the code

Make sure you download and save to your Arduino/Libraries folder TinyGPS.h
and NewSoftSerial.h files.
