Here are some features and details about John Deere Connected Support

WE ARE WORKING TO HELP WITH MORE EFFICIENT WAYS TO COMMUNICATE
With Service ADVISOR™ Remote, your dealer can remotely analyze Diagnostic Trouble Codes (DTCs) in near real-time to isolate potential issues with your machine.
When it’s convenient for you, a technician will arrive with the right parts and tools to get you back up and running.

PREVENT DOWNTIME WITH PREDICTIVE DIAGNOSTICS
An industry exclusive, Expert Alerts is a proactive monitoring system that notifies dealers (with a customer's permission) of potential machine issues.
This allows technicians to diagnose issues remotely and fix them before they become a problem.

RIESTERER & SCHNELL SUPPORT IN REAL TIME
Distance is no longer a barrier with Remote Display Access.
With your consent, this advanced solution enables technicians to remotely connect to the display in your cab to help you make near real-time adjustments to optimize your machine for changing conditions or to troubleshoot potential issues.
To enable Remote Display Access, your machine must be factory-equipped or field-installed with the following:
Gen 4 or GreenStar™ 3 (GS3) 2630 Display
JDLink™ Access + RDA or JDLink Connect Activation
MTG/JDLink-Equipped Machine
Ethernet Cable
Also make sure you have a valid MyJohnDeere account and appropriate partnerships set up in the John Deere Operations Center. Contact your local Riesterer & Schnell location if you have questions or want to learn more.
