Why does my Navman GPS say 'GPS FIX LOST'?
The 'GPS FIX LOST' message on your Navman GPS indicates that the device can no longer establish a GPS fix. This often happens when the antenna's view of the sky is obstructed. To resolve this, make sure the antenna has a clear view of the sky.
What to do if my Navman GPS Tracker500/500i switches itself off?
If your Navman GPS Tracker500/500i is switching off unexpectedly, it could be due to a poor connection in the power cable, leading to intermittent power loss. Also, the device will shut down if it detects a large voltage surge to protect itself. Check for loose battery connections. You should check the connections and power supply.
Why does my Navman GPS take so long to get a fix?
If your Navman GPS Tracker500/500i takes a long time to get a GPS fix, it may be because the device has been moved more than 500 kilometers since it was last switched on, or it hasn't been used for several months. To solve this, allow the Tracker500/500i to search the sky for all available satellites.
How to fix Navman Tracker500/500i GPS fuel remaining if it does not match the amount left in the tank?
If the 'Fuel Remaining' reading on your Navman GPS doesn't match the actual fuel in the tank, it's likely because the setting wasn't properly calibrated after refueling. You should calibrate the fuel transducer and set Fuel Remaining after every refuel.
How to fix Navman GPS Tracker500/500i if it will not switch on?
If your Navman GPS Tracker500/500i won't switch on, the power or data cable may not be properly connected to its socket, or the power supply connections might be reversed. Check connections.
Why are my Navman Tracker500/500i fuel flow readings erratic?
Erratic fuel flow readings on your Navman GPS can be caused by the fuel flow transducer being mounted too close to the fuel pump(s) or being subject to excessive vibration. Check for air leaks and adjust the FLOW FLTR value until a steady flow rate is indicated.
Why is my Navman GPS Tracker500/500i position off by 100 meters?
The position indicated on your Navman GPS Tracker500/500i may vary by up to 100 meters from the true position due to Selective Availability (SA), a varying offset introduced by the USA Department of Defence. If available in your area, install a differential receiver.
Why does my Navman GPS indicated speed not match the boat's speed?
If the indicated speed on your Navman GPS doesn't match your boat's speed, it's likely due to the constantly changing Selective Availability (SA) offset, which typically causes an error of less than 1 knot but can occasionally exceed 1.5 knots. Connect the Tracker500/500i to a differential receiver.
Why does my Navman Tracker500/500i indicated heading not match the boat’s compass?
If the indicated heading on your Navman GPS doesn't match the boat's compass, remember that the boat must be moving for the device to determine direction. The constantly changing SA offset results in an indicated heading error, usually apparent only at low speeds. Set the Tracker500/500i BEARINGS setting to MAG.
What to do if Navman Tracker500/500i indicates no or low fuel flow?
If your Navman GPS indicates no or low fuel flow, check that the 5 pin fuel transducer connector is fully inserted into its socket on the back of the Tracker500i. Also, check connections and ensure fuel filter(s) are clean.
