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 to a vehicle in
a location where the sky can be seen well.
When initially connecting the GPS, it usually takes about 10 minutes to be normally
operating, 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 followings.
• Check if the power is connected to the product.
• 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.
• Please make sure it is changed to the start point for simulation at MENU > Route > New

Start Point.

Cannot hear the voice guide.

You can hear the voice guide when you select the “MENU > SETUP > Volume”.
But during actual driving, the voice guide is provided.
If the volume is too low, adjust the volume on the left side.
If the volume is mute, press the AV OFF button on the right side.

There is a difference between the driving road and the road on the
map in the product.

Even though GPS is usually very accurate, it has an error range.
When GPS receiver is installed, there can be an error of about 5 to 15m.
But for newly constructed roads, the problem could be 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. Newly install the data again.
If the issue persists after the installation, contact your supplier.

Map data and dangerous area information are not newly updated.
You must periodically update the map data.
Refer to the homepage for details on how to update the data.

If you have other questions about the Navigation Device, please contact your
supplier or Technical Support:
