A couple of years ago I purchased a 587ci that works great and I purchased a navionics SD card at the same time for a particular water system that also works great. However, I have noticed that when the screen moves into the the boundary edge of the mapping software, the chart disappears. If I zoom in, thus moving the boundary outside the screen, it comes back. This is really annoying as there are many places where I am boating that are close to that boundary. Even just panning around, if the screen encroaches at all on the boundary of the chart map, the chart disappears and I am left with the built in base map, which is useless and completely inaccurate.
Anybody else have this happen and is there a fix.
Thanks
