The GM300 and the M120 are the same series of radio. The M120 is just the limited version, not unlike the Maxtrac 50 compared with the Maxtrac 300. Look here for the pinout of the accessory connector for the 8 channel radio (which use a masked logic board) or 16 channel radio.

If you want to use the COS/COR output from your GM300 the COS/COR on pin 8 is (active low). Many interfaces need a COS/COR input that is (active high) at 2 to 5vdc. You can make up a circuit to convert the output from pin 8 or take a COS/COR output from inside the radio that will give you a (active high) output. You will need to access the logic board on the underside of the radio. Remove the front of radio and the bottom cover and lift off the RF shield. See photo below.
