tide data on cmap

[galeus]

I have a Standard Horizon 300C Chartplotter and had a final update in 2018 for my Cmap chart SD card.
Each year since I have been able to access tide data anywhere in the UK for any given day.
This year that feature needs me to correct the 2006 date that is the default? and enter the date I want and this seems to work, but it won't remember the info you just gave it.
Next time you go on to tide data it asks the same question.
Is that because Cmap have stopped supplying this info, or any other ideas?

It's due to the GNss module returning the wrong date . I replaced mine with one on amazon, I think less than £8. Just need a bit of soldering and changing the new gnss module baud rate to 4800. See Standard Horizon cp300 date problem for more info
