Sending GPS data to mobile via bluetooth

Brad's definitely right. Here is some code from the SoftwareSerial example sketch.

#include <SoftwareSerial.h>

SoftwareSerial mySerial(10, 11); // RX, TX

void setup()  
{
 ...
  // set the data rate for the SoftwareSerial port
  mySerial.begin(4800);
  mySerial.println("Hello, world?");
}

You should add (in your case) "ss.begin(nnnn)" with the appropriate baud rate for talking to the GPS.

Cheers
