Automatic Distance Correction Check - Panasonic CN-DV2300N Operating Instructions Manual

●The mobile navigation system uses GPS data for distance correction. Make sure that
GPS signals are being received (checking for GPS reception is described on this page).
●Check GPS reception in an open area location.

■Automatic distance correction check

●
In the following cases, drive the vehicle in an open area for approximately 30 minutes at a speed
of over 12.5 mph (20 kmph), while receiving GPS signals. This should be done after re-setting the
learning results from position correction (accuracy level) in order to improve the GPS distance
correction accuracy (with the GPS reception indicator illuminating on the map screen).
Refer to "Automatic Distance Correction" for details for distance correction for the items below
( page 32).
1. When using the navigation system for the very first time after installing the system
2. When the navigation system is transferred to another vehicle
3. When the tyre pressure is changed, tyres are changed, tyres are shifted in rotation or a spare
tyre is used
4. When deleting the position correction learning results for some reason
Notes
●Do not start driving until the opening screen and caution screen close.
●The vehicle position indicator may disappear temporarily after the speed is increased
depending on the vehicle model. This is a normal phenomenon indicating that the system
is calculating the distance correction.
