Neo 6m GPS outputting special characters in serial monitor

[jnp843]

Hello, I am using a raspberry pi pico and the arduino IDE to get GPS positions using a neo 6m GPS module but when I check the serial monitor the strings outputted have alot of special characters in them like this:

$GPRMC,150506.00,A,3020.60871,N,00249.45087����������������������������������������������L)��bZ����5)�A����������������������9�������ijpnX�XbXbXb\dbXbnr\dX�Xjb\fX�XXThpH����A,A,3,12,24,25,32,19,10,22,15,17,06,,,1.81,

Heres the code im using to check my GPS works:

#include <SoftwareSerial.h>

SoftwareSerial mySerial(5, 4); //(RX, TX)

void setup() {
  mySerial.begin(9600);
  Serial.begin(9600);
  Serial.println("GPS start");
}

void loop() {
  while (mySerial.available()) {
    Serial.write(mySerial.read());
  }
}

The GPS module im using is this: https://www.amazon.co.uk/dp/B0BJ6CRS3R/ref=sspa_dk_detail_1?psc=1&pd_rd_i=B0BJ6CRS3R&pd_rd_w=8Byfa&content-id=amzn1.sym.15c0cc83-c6c5-4d44-aa3d-0de17a9f3682&pf_rd_p=15c0cc83-c6c5-4d44-aa3d-0de17a9f3682&pf_rd_r=Q64ETJ5KMY97BJY3YM2H&pd_rd_wg=k03gc&pd_rd_r=0f785dfd-82ba-4e7f-aa6a-de53e88e8979&s=electronics&sp_csd=d2lkZ2V0TmFtZT1zcF9kZXRhaWw

I have tried the module outside aswell and it produces the same results.

Does anyone know what the problem could be?

Thanks

What baud rate is the Serial monitor set to ?

Its at 9600, I have also tried lowering it and raising it but more characters appear.

I wonder if SoftwareSerial is acting up. Does the raspberry pi pico have a second hardware serial port you could use instead?

Have you tried using the U-Center tool to talk to it?
