I have Navionics Gold Japan and Pcific Ilands in both 2010 and 2011 edition in my iPad.
When I see chart list, I can't recognize which is which..
Is there any way to get the chart info?
And is there way to delete the older one from iPad?

These steps should help you delete and remove the older region..
