<Learning>: The system has started learning
calibration data.
<Learned>: Though learning is almost complete,
the system is still learning to make the calibration
data more accurate.

Reset the data if you replace the tires or if the
current position is displayed far from the actual
position

* 1 About calibration
The calibration is a function conducted in order to
display the current position more accurately using
signals from GPS and the internal sensors.
Even after calibration status changed to
<Learned>, the system will keep learning to make
the current position more accurate.
• The calibration does not function without the
connection of GPS antenna and the speed signal
lead. For the connection, ☞ Installation/Connection
Manual (separate volume).
• Driving under various conditions completes the
calibration faster. If <Learning> remains on the
screen for a long period, check the connection of the
GPS antenna and the speed signal lead.
• While learning is going on, the current position may
not be displayed correctly .
