The GEONAV does not turn on
Make sure that the unit is powered with voltage between
10 and 18 VDC. Check the polarity of power supply.
The GEONAV does not get any valid satellite fix
Make sure that no metal obstacle is positioned around the
unit acting as a shield for the GEONAV antenna. If after 40
minutes the GEONAV does not get a valid fix, then turn the
unit off and on again.
The GEONAV screen gets dark after a long exposure to direct sunlight
Adjust the contrast.
The GEONAV does not respond to any key
Turn the unit off, then on again; if the problem continues,
erase the memory by turning the unit on while keeping the
CLR key pressed. This operation will delete all the data (route
and setting) previously saved in memory.
