Ok, so as far as the app goes I'm back up and working 100%.
I had to completely re set the app which deleted everything automatically. Then re downloaded my required area. Now to go to the boat and place it on the plotter.
I will have to do this in reverse. I have an sd card that @jonnyswampgave me, it's full of marks for the Solent. I will transfer those to a micro sd, then put them in the plotter that way. I just hope they are the correct format?
My marks have defo disappeared from the plotter. 100%.
And I'm unable to delete the maps off the app. I've been into settings, gone to delete all on the chart, pressed delete, nothing happens.
That's just the thing Ian, I did delete the charts. Think that's why I also lost all my Marks. I'll have another try tomorrow . Don't think I'll bother next year, I'll just use the old out of date chart.
Yea it's me I'm 100%. It's something I only do once a year so not a thing that sticks in the head. As you know I'm a manual person not a techie nerd like you!
