same issue / same Garmin unit.

I ended up needing to buy the BLUE CHART G3 Vision Card.
The factory loaded software while it shares a similar name is missing THE NAVIGATION part of the software.
So I bought the G3 vision card with the "High-resolution Relief Shading" and it was a serious upgrade and worth it.
