GPS - SAT Com status LED

So... I am on phase II of a embedded tracking device. I wish to give the user some feedback about the SAT com. I noticed the EM-406 has a status LED. Anyone have any suggestions to mimic that behavior, or know how circuit works? My device has a microcontroller on board, but is there anything I can do besides query the GPS module from the microcontroller to check the SAT locks?

Thnx

The only ways I can imagine that are reasonaly easy would be to solder onto that LED or to read in the position fix indicator of the GPGGA command.
