"The Dexter Industries dCompass is a compass sensor for LEGO MINDSTORMS NXT. This compact sensor detects magnetic fields for navigation. Using a magnetic sensor, the sensor is able to measure the earth's magnetic field and returns a magnetic heading, telling you which way your robot is heading.You can buy the dCompass on Amazon or on the product page.
The device can be used without calibration and can be calibrated with software to account for magnetic fields to deliver a highly accurate compass heading.
The sensor is supported in NXT-G, Labview, and RobotC.
The sensor communicates with the NXT via I2C and can be placed on any port."

Honestly, I don't know, but I asked John Cole (CEO of Dexter Industries) and this is what he said:
