    Hi,

    I have tried your nmea data stream & it does not show location for me either.

    On the end of each string is a checksum, here in this example it is 76
    Code:
    Please Login or Register to see the links
    save this as text & load in to VisualGPS & you will see the location. If you change the checksum, it will not show

    Checking here [Only registered and activated users can see links. ]

    ( enter string data between the $ and the * )

    For some reason on your $GPGGA strings & others when the checksum is a single digit it displays for example 5 instead of 05 (zero 5).

    So when I change the checksum of one of your $GPGGA string from 5 to 05 it now displays correctly.

    Possible things to try
    ---------------------
    1/

    I noticed on your nmea $GPZDA string, the date 30 sept 2000
    Code:
    Please Login or Register to see the links
    Try finding out what is causing this, Phone maybe, and set the correct date.

    2/ try a different app to Gps over bt

    3/ try an app that will pass GPS via a usb connection
