CHAPTER 13 - TROUBLESHOOTING
No Sound from the Speaker
•
If the GNAV20 is plugged into the cigarette lighter adaptor and the switch is in the ON position,
and you are still not getting power, you should unscrew the tip of the power plug and check the
fuse. If the fuse is blown, you should replace it with the same value fuse.
•
If the fuse is not damaged, or if you have to replace the fuse repeatedly, please call our help line
0870 873 0080 for further assistance.
•
Is the volume knob on the GNAV20 is turned to the halfway mark?
•
Go to the Volume Control screen under the SETTINGS menu and adjust the volume to 5 or
higher
Unit Beeps at Startup then is Silent
•
The expert mode has been activated. To turn the expert mode OFF:
1.
Say, “
navigator
(
beep
)
Settings
”
2.
Answer, “
No
” until the GNAV20 asks, “
Do you want to turn OFF the expert mode?
” then
answer “
Yes
”.
No Response to Commands
•
If the navigation unit is not responding to your commands try relocating the microphone closer to
your mouth. Remember to clip the microphone to an object, like your seatbelt shoulder harness.
•
Wind and fan noise, as well as talk radio stations can “confuse” the voice recognition software, so
turn the radio off, roll up your windows, and turn your fan to a lower setting when entering
information.
•
If the GNAV20 still does not respond, please call our help line 0870 873 0080 for further
assistance.

GPS is Not Available
•
Is the antenna positioned on a metal surface, preferably the roof of your vehicle? Some vehicles
have window film with metal properties that block the GPS signal. If you have placed the GPS
antenna on the inside of the vehicle you will have to reposition it to the outside.
•
If the GNAV20 has been turned off for a while it takes a few minutes to “find” the GPS signal. It
can take up to 15 minutes in extreme cases.
•
If the GNAV20 does not locate the GPS signal after 15 minutes, restart the system.
•
If the GNAV20 still has not picked up the GPS signal, call our help line 0870 873 0080.
The GNAV20 is Slow Responding to Commands
•
Was the GNAV20 left in an environment that was too hot or too cold? This navigation system is
designed to operate b40 degrees and +112 degrees Fahrenheit. When starting the
GNAV20 in very cold or very hot weather, you may have to use the vehicles heater or air-
conditioner to bring the temperature into the proper range.
The GNAV20 Does Not Recognize an Address
•
Sometimes a new street is constructed after the map database has been updated. Also, some rural
areas and small towns are not detailed, and only major intersections are listed. Try navigating to
a major intersection near the address.
The GNAV20 Does Not Recognize an Place Name
•
This typically happens with restaurants, as every year many restaurants either go out of business
or change names. If the GNAV20 does not recognize the place name, try using the address
instead.
