Hi,
My friend has a Globalnav 3000 C This is installed on a boat he recently
purchased.

The unit seems to work fine, reads satellites, shows correct position on
the cartridge charts etc. etc.

However I would like to check the software as I do not believe it has
ever been updated since new.

Problem is I cannot get to the main menu to access the system menu.

I have read the manuals thoroughly and the command to get to the main
menu just does not work. I can access the secondary menus but not the main
menu.

Has anybody out there any experience with this kind of problem?

Thanks
Oliver Fleming
