I spoke with my associate and he recommends you load and purchase both raster and vector charts.
The best Vector choice is MM3-VNA-027 and the best Raster choice is MM3-R91-2G0. The reason for needing both charts is because the Raster provides better accuracy and the vector charts provide more detail and more information. The vector charts have many more updated marinas and other details that the Raster charts do not.
You might also check to make sure you have some additional databases loaded. They are at no charge.
They are MM3-UST-002 and MM3-UST-003. These are the 3D data and may already be in your MFD. They would be listed as SDUS02MAP3D04 and SDUS03MAP3D04 respectively. Finally check for SDVJWW00MAP02. (Our part #MM3-WVJ-000) This is the Jeppesen world base map which will be necessary when viewing the vector chart pack MM3-VNA-027, which is a Jeppesen database.
