At the risk of sounding simplistic and not really sure of the effect, have you tried altering the baud rate to 4800. Some nav programs require this and will not recognise 9600 bps which may the fixed output of your BU353 GPS mouse thingy!If the program does not allow for 4800 use an older GPS via RS232 to check.
Hope I have been of some help!
