in the program from 2.50 to 2.51 and saved it with the same name. I then copied this to the Nuvi (after removing
the original GUPDATE.GCD) and rebooted it.
Perhaps I should have made it 5.01 since the original was 5.00 but I assumed that 'a change' is 'a change'.
It did tell me that it was an older version and after I had acknowledged this it proceeded.
Finally it reported SYSTEM SOFTWARE MISSING and will not continue or acknowledge any USB connection.
Apart from GARMIN these are the only words on the black startup screen.
Where did I go wrong?
