Troubleshooting 

GPS400 User Manual 

 

If you’re experiencing difficulties with your Voxson GPS400, please refer to the below list of solutions to 
common problems.    If you can’t find your particular issue below, contact customer support on 1300 889 

990 or 

.    Also refer to the frequently asked questions in the next section for 

answers to the most common questions relating to the GPS400 and GPS navigation in general. 

 

Should your GPS400 freeze or become unstable, insert a straightened paper clip or pen tip into the Reset 
switch located on back of the device. The device will then restart. 

Hard Reset: Slide the battery switch off then to perform a cold boot or hard reset. This procedure will 
restore the factory default settings of the device.    You will not lose any addresses you have saved to your 

favourites or trip planner. 

 

If your GPS400 device will not turn on it may be due to lack of power.    Check that the battery switch on 
the back of the unit is turned on, and that the charger cable is plugged in.    If using the car charger, 

ensure that the light on the charger is on and if it is not, check the vehicle’s cigarette lighter socket.    The 

Unit should remain connected to the charger whenever in the vehicle to ensure that your GPS400 is 

always adequately charged. 

 

The primary cause for your position to not be updated on the map is the GPS receiver does not have 
adequate signal from the satellites.    Low signal can be easily identified by the voice prompt “Signal too 

low” and the triangle representing your position having a cross through it 

.    This is commonly caused 

by obstruction of the GPS receiver in the form of overhead bridges, tunnels, tall buildings, severe weather 

conditions, dense tree cover, etc.    The signal level being transmitted from the GPS satellites is extremely 
low and although the GPS400 is fitted with a highly sensitive antenna, it is still essential that the unit has 

a clear view of as much of the sky as possible.    If your unit continually loses signal, check the installation 

location in the car.    It may be necessary to use an optional external antenna to achieve better signal 
reception in your particular vehicle application. 

Please note that when you first turn your GPS400 unit on in an open area, it may take up to 15 minutes to 
receive adequate signal.    This time may be greatly increased if you are moving during the initial signal 

acquisition. 

 

It is important to turn put your GPS400 in standby mode whenever you are parking the car and turning 
the ignition off.    Use the power button on the top of the unit to activate standby mode.    In standby mode 

the backlight and processor are switched off to conserve power however the battery may still discharge 

over a period of several days.    For long term storage (weeks) it is best to switch the unit off at the 
battery switch to maintain some charge in the battery.    This will prolong the battery life.
