TM-D710GA - iGPS appears, then goes off


I am hoping someone can provide some insight I am having with my TM-D710GA.

When the radio is powered on, the iGPS indicator will come on for two or three seconds, the turn off. I can press the function key "GPS" and the iGPS indicator will come on, but then turn off again.

Both A and B radios are working and I can receive APRS packets.

Any idea what is happening here?
