The following is a brief guide to some of the problems you may experience while using the Geopilot
II Plus with common solutions.
15.3.1 Power
no Power — The power connections are loose or not fully engaged. Make sure all Power Cable
connections are secure. Make sure the power supply is operating properly. Check the fuse located
at the end of the cigarette plug. (To open unscrew the middle circle at the tip of the adaptor.)
15.3.2 GPS fix
Position fix doesn't change — The signal from one or more satellites has been lost; the positioning
information displayed is the most recent available.
Position fixes vary a lot — GPS accuracy is affected by several variables, the most prevalent of
which are the geometric quality of the fix. Therefore, the specified accuracy of 15 Meters RMS
in 2D is statistical, not absolute and assumes the absence of Selective Availability which was
discontinued in April 2000.
The Geopilot II Plus is not obtaining position fixes — If the Geopilot II Plus is using an internal
GPS Receiver, proceed to the GPS status screen:
>'MENU' 1 sec. + "GPS PAGE" + 'ENT'
Review the number of satellites in use. If zero, check that the antenna has a clear view of the
sky and that the connections have been made properly. If less than four satellites are in use, the
GPS receiver may have difficulty receiving a fix. Try repositioning the antenna. A GPS fix requires
a minimum of three satellites and a poor Signal Quality on one or more satellites may preclude
receiving a position fix.
Verify the user setting for Fix Source is listed as Internal GPS:
> 'MENU' 1 sec. + "SYSTEM SETUP" + 'ENT' + "FIX SETUP" + 'ENT' + "FIX SOURCE"
+ 'ENT' + "INTERNAL GPS" + 'ENT'
If the Geopilot II Plus is using an External GPS receiver, proceed to Fix functions screen:
> 'MENU' 1 sec. + "SYSTEM SETUP" + 'ENT' + "FIX SETUP" + 'ENT'
