GENERAL PART (Navigation)
Cannot identify the current location. (GPS not receiving)
GPS cannot be used indoors and must be connected to the power with ACC in a vehicle in a location
where the sky can be received easily.
When initially connecting the GPS, it usually takes about 10 minutes to be working normally, but the connection speed can differ depending on the weather condition, and surrounding obstacles.
If the GPS connection is unstable for a long period of time, try the following.
• Check if the product is connected to a power source.
• Check if the back of the GPS product is in a location where the sky can be seen well.
• If there are high buildings or if you are under a tree, move to a location where there aren’t
any obstacles.
• Check the GPS receiving condition from the GPS menu.
Cannot hear the voice guide.
Check that volume is set to Mute to very small volume in the setup menu.
No guide sound comes out in the case of straight sector or not in the guide time.
In this case, an appropriate sound in the current position if pressing the NAVI button.
There is a difference between the driving road and the road on the
map in the product.
Even though GPS is usually very accurate, there is a small margin for error.
When the GPS receiver is installed, there can be an error of about 10m. But for newly built roads,
the problem could come from the data update to the map.
Cannot see the map.
Perhaps you cannot see the map even when you have executed the navigation menu.
This happens when the data within the memory is damaged. Delete all the data in the memory and install
the data again.
If the issue persists after installation, contact the A/S center.
9-1
The path guide can be different from the actual path.
(Path guide error)
• When the road is closely parallel.
• When the splitting road angle is very small.
• When there is an adjacent road when turning.
• When driving on a road that is narrowing fast.
• When driving through the mountain or where the road is too curvy.
• When the starting, passing and arriving locations are too close within 1km.
• When you have set the starting, passing or arriving location more than 1km away from
the road.
• When driving through the tunnel.
Map matching
As mentioned, the GPS systems used by this Mobile Navigation System are susceptible to
certain errors. Their calculations may on occasion place you in a location the map where no
road exists. In this situation, the processing system understands that vehicles travel only
on roads, and is able to correct your position by adjusting it to a nearby road. This is called
map matching.
With map matching.
With no map matching.

Symptom
Power doesn’t turn on.
The unit doesn’t operate.
Cause
Correction
• Leads and connectors are not
properly connected.
• Confirm once more that all
connections are correct.
• The fuse is blown.
