Arduino Mega not receiving data from Neo-6M

Question

I am using the trying to get data from the Neo-6M GPS module with an Arduino mega, but, the condition 'While (gpsSerial.available()> 0' is being met. I believe this means the no bytes are being transferred from the module to the serial port but I'm not sure why. The light on the Neo-6M was blinking which means it getting a lock but not giving out the data.

#include <SoftwareSerial.h>
// Choose two Arduino pins to use for software serial
int RXPin = 19;
int TXPin = 18;
//Default baud of NEO-6M is 9600
int GPSBaud = 9600;
// Create a software serial port called "gpsSerial"
SoftwareSerial gpsSerial(RXPin, TXPin);
void setup()
{
 // Start the Arduino hardware serial port at 9600 baud
 Serial.begin(9600);
 // Start the software serial port at the GPS's default baud
 gpsSerial.begin(GPSBaud);
 Serial.write("123");
}
void loop()
{
 // Displays information when new sentence is available.
 while (gpsSerial.available() > 0)
 Serial.write(gpsSerial.read());
}

I had it working on an Uno by connecting to pins 2,3 rather then 18 and 19. I have also tried swapping the 18 and 19 pins over but still noting.

Thanks for the help

EDIT: I have the RX and TX plugged into the mega at pins 1 and 2, however, it will only print GPS information when the reset button is pressed or held down

Not all pins on the Mega support software serial, have a read below:

Pins 18 / 19 are actually hardware serial pins so should not need the use of software serial.

Edit, should have noted to use hardware pins 18 / 19 you would use the constructor Serial1.begin(9600)
