Cannot identify current location. (GPS not receiving)

GPS cannot be used indoors and must be connected to a power source with ACC in a vehicle in a location 
where the signal from the satellite 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 your vehicle 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 are no obstacles.

Cannot hear the voice guide.

The volume is not set correctly or turned off. Adjust the volume of voice guidance.

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. Please reset all settings related with navigation.

The path guide is 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 mountains 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 locations more than 1km away from the road.
• When driving through tunnels.
