Upgrading Farmnavigator G7 plus with DIY Autosteer

Hello everyone,

I am writing to you because I would like to know if it is possible to upgrade the existing AvMap Farmnavigator G7 Plus navigation system with a home-made Autosteer system. So, I would like to upgrade all the necessary hardware (motor, motor driver, mechanical parts and necessary electronics) myself. The navigation system already has an Enthernet output ready for the Autosteer upgrade, which can be purchased as standard. In particular, I would like to know if anyone has experience with this, how I could use the data from this Enthernet port and integrate it in my home-made autosteering. I attach two more pictures of all outputs to help you get an idea.
