Questions
if I have a Vulcan 7R in my network, really need an extenal GPS? Which benefits give it to me?
While the Vulcan 7R does have an internal GPS antenna, there are certain installation applications (such as in a cabin, etc). where the signal is not well received by the display itself. In these cases you would require the external antenna. This antenna also has a heading sensor, which provides better accuracy on heading information (gives a true heading, rather than relying on GPS information) and can support additional features that require this accuracy.

This unit should not be used for a sailboat autopilot system, correct? And why?
Not designed for Autopilot/MARPA: The ZG100 is explicitly stated as "not suitable" or "not recommended" for autopilot control or MARPA (Mini Automatic Radar Plotting Aid) by B&G and various vendors.
Need for Rate Compass: For these functions, a dedicated rate compass like the Precision-9, RC42, or Halcyon Gyro-Stabilized Compass is required.
Heading data limitations: While the ZG100 provides heading data, this information is not precise enough for the demanding requirements of an autopilot system, which requires accurate and fast heading updates to maintain a steady course.
Potential issues with accuracy: Using the ZG100 for an autopilot could lead to unstable steering and poor course-holding performance, especially in changing conditions.
The ZG100 is designed to provide high-accuracy position information and heading for radar chart overlay and chart stabilization in Head Up mode. However, it lacks the precision and update rate needed for reliable autopilot or MARPA control.

Is this compatible with a Vulcan 12r
It’s NMEA2000 so yes. Just plug it into your network then select off device list.
