How to get Parallax PMB-648 GPS module working with Arduino UNO?

jeffmorris:
Any suggestions?

Try this to see what data, if any, is arriving from the GPS:

#include <SoftwareSerial.h>

SoftwareSerial nss(6, 255);            // Yellow wire to pin 6

void setup() {
  Serial.begin(115200);
  nss.begin(4800);
  Serial.println("Reading GPS");
}

void loop() {
  if (nss.available()) {
    Serial.write(nss.read());
  }
}
