I'm looking to put a overlay map on my elite 7 HDI. I have watched several videos that use SAS.planet and insight to achieve this. The area that I fish the most is Port O'Connor, does anybody have or know of a map that is post Harvey? Google earth is still pre-Harvey and the other map pictures were taken on windy days to where you really cant see the structure until your zoomed in to far to navigate with.

Also, is it about the same processs as the HDS?

the way I understand it, with my HDS7 is i had to run the navionics platinum plus chip to get the satellite overlay. all my images on the gps are post harvey. it shows sunday beach blown out and a few of the other cuts and drains. but like yours with the windy days when they took the pictures some areas do have to be zoomed way in on. mainly just the reefs.
