I have just fired up an old JLR 4510 GPS
which has not been used for about 8 years. Was working fine when mothballed. Put a new battery
in, performed a master reset and entered correct data in set up.
It took hours to produce a correct position. In the process lots of the info that I had put in during setup was changed. Eg. it is now indicating 11th day of 7th month 1990.
Did these units have a problem with the change of centuries?
Is there something else that can be done to make it work
Does it matter that the settings are incorrect, if the position readings are OK or should I junk it and get a new one?
