From my experience, find a big open parking lot and do several slow speed
360 degree circles (like 4 or 6). The instructions in the 2012 GC Owner's
Manual are:

Automatic Compass Calibration
This compass is self-calibrating, which eliminates the
need to manually reset the compass. When the vehicle is
new, the compass may appear erratic and the EVIC will
display CAL until the compass is calibrated. You may
also calibrate the compass by completing one or more
360–degree turns (in an area free from large metal or
metallic objects) until the CAL indicator displayed in the
EVIC turns off. The compass will now function normally.
NOTE:
A good calibration requires a level surface and
an environment free from large metallic objects such as
buildings, bridges, underground cables, railroad tracks,
etc.

Compass Variance
Compass Variance is the difference between Magnetic
North and Geographic North. To compensate for the
differences the variance should be set for the zone where
the vehicle is driven, per the zone map. Once properly
set, the compass will automatically compensate for the
differences, and provide the most accurate compass
heading. For the most accurate compass performance, the
compass must be set using the following steps.
NOTE:
Keep magnetic materials away from the top of
the instrument panel, such as iPod’s, Mobile Phones,
Laptops and Radar Detectors. This is where the compass
module is located, and it can cause interference with the
compass sensor, and it may give false readings.
1. Turn the ignition switch ON.
2. Press the UP or DOWN button until the Setup
(Customer-Programmable Features) menu is reached,
then press the SELECT button.
3. Press the DOWN button until the “Compass Variance”
message is displayed in the EVIC, then press the SELECT
button. The last variance zone number displays in the
EVIC.
4. Press and release the SELECT button until the proper
variance zone is selected, according to the map.
5. Press and release the BACK button to exit.

Manual Compass Calibration
If the compass appears erratic and the CAL indicator
does not appear in the EVIC display, you must put the
compass into the Calibration Mode manually, as follows:
NOTE:
For the most accurate compass performance, the
compass variance must be set before performing the

manual compass calibration. The variance should be set
for the zone where the vehicle is driven, per the zone
map. For further information, refer to “Compass Variance.”
1. Turn ON the ignition switch.
2. Press the UP or DOWN button until the Setup
(Customer-Programmable Features) menu is reached,
then press the SELECT button.
3. Press the DOWN button until “Calibrate Compass” is
displayed in the EVIC.
4. Press and release the SELECT button to start the
calibration. The “CAL” indicator will be displayed in the
EVIC.
5. Complete one or more 360–degree turns (in an area
free from large metal or metallic objects) until the “CAL”
indicator turns off. The compass will now function
normally.

I had the same problem. Then I went to a supermarket parking lot and did the circle thing. After about 2 minutes it stopped blinking.

Even though you have calibrated, you still need to make sure the variance is set correctly. It is one of the last settings in the EVIC. On my 2011 GC, the variance map was in the owners manual. In my 2013 GC, the variance map is missing. I had to search online to find one. If you don't set the variance, your compass will seem to work, but will be off depending on how far east or west you are of its default, which is in the mid-west. I have linked a jpg of the map to this post for everyones future reference. Mine was originally set to region 8 or 9, but I live in region 11.
