How to use FM Radio on SIM808 EVB-V3.2.2

Question

I Just bought the SIM808 GSM/GPRS/GPS shield with an arduino Mega 2560. I have written a simple sketch shown below which I'm using to execute AT commands on my SIM808 shield.

#include <SoftwareSerial.h>

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

void setup()  
{
  // Open serial communications and wait for port to open:
  Serial.begin(9600);
  mySerial.begin(9600);

}

void loop() // run over and over
{
  if (mySerial.available())
    Serial.write(mySerial.read());

  if (Serial.available())
  {
    while(Serial.available())
    {
      mySerial.write(Serial.read());
    }
    mySerial.println();
  }
}

I keep getting ERROR as a result of executing the AT+FMOPEN=1 command which is used to initialize the FM Radio integrated with the module. So far, all other AT commands works great except this one.

My SIM808 Module looks like this:

The FM Feature is only available on the SIM800, SIM800L,or SIM800H. Sadly the SIM808 does not have the FM Radio feature according to the datasheets.
