Platinum would be much like the MapMedia charts with the Sat photo fusion overlay. You can get about the same type of presentation, but ultimately Navionics platinum and C-map reveal are not designed or supported in these units. These machines use MM3 charts with different data options like CMOR/Data core by C-map/Navionics/National Hydrographic office/Army corp river charts. Much of what is available varies depending on the area of operations. As we have said many times, it is best to contact Technical support with a Lat/Lon for some sample screenshots of what is available for a particular area. The TZT3 customers with DFF3D have the option to make their own 3D bathy.
