Acura 2010 RDX - Manual (Page 300)

Compass Calibration
If the compass direction is blinking
and the CAL indicator is shown, the
compass is self-calibrating.
The compass may need to be
manually calibrated after exposure to
a strong magnetic field. If the
compass seems to be continually
showing the wrong direction and is
not self-calibrating, do the following.
NOTE: Do this procedure in an open
area, away from buildings, power
lines, and other vehicles.
1. Press and hold the SOUND/
CLOCK and RPT buttons at the
same time for about 2 seconds.
You will hear a beep, then the
display will change to the compass
setting mode as shown above.
