U0586Invalid Data Received from Navigation Display Module

Q: What does code U0586 mean?

Invalid Data Received from Navigation Display Module. U0586 means the vehicle's network gateway or control module expected a valid data message from the navigation display module and received corrupted, missing, or out-of-range information instead. The computer detected a communication fault on the controller area network (CAN) bus specifically tied to the navigation display, not a failure of the display screen itself.

Symptoms you may notice

Navigation screen may freeze, go blank, or show outdated position information
Radio or media functions may become unresponsive or reset intermittently
A warning light or message on the instrument cluster indicating a communication fault
Often no symptoms besides the warning light, especially if the navigation display still powers on
Steering wheel controls or voice commands for navigation may stop working
Battery drain if the navigation module stays awake due to a bus fault

Common causes, most likely first

Corroded or loose electrical connector at the navigation display module
Damaged or chafed wiring in the CAN bus circuit between the navigation display and the gateway module
Failed navigation display module internal communication circuit
Low battery voltage or poor ground connection causing intermittent data corruption
Aftermarket accessory wired into the navigation or CAN bus circuit causing interference
Software glitch or failed update in the navigation display module
Water intrusion into the navigation display or its connector

How to diagnose and fix it

Verify battery voltage and charge the battery if it is below 12.4 volts, then clear the code and retest
Inspect the navigation display module connector for corrosion, bent pins, or loose fit and clean or reseat as needed
Check the CAN bus wiring between the navigation display and the gateway module for continuity, shorts, and chafing
Perform a voltage drop test on the navigation display ground circuit to confirm a clean ground
Disconnect any aftermarket accessories wired to the navigation or CAN bus circuit and retest
If wiring and power are good, substitute a known-good navigation display module and clear the code
Check for and apply any available software update for the navigation display module before replacing it

What the navigation display code really means

U0586 is a network communication code, so the navigation screen can look and work perfectly while the module still sends invalid data that sets the code.
A weak or failing battery is a common hidden cause because low voltage corrupts CAN bus messages and triggers U0586 without any navigation complaint.
Aftermarket phone mounts, dash cameras, or charging cables routed near the navigation display wiring can induce interference that mimics a failed module.
Technicians who replace the navigation display without first checking the ground circuit often find the code returns because the real fault was a poor ground.
This code does not mean the navigation map data is outdated or that the GPS antenna has failed; those faults set different codes.

Can I keep driving with U0586?

The vehicle remains safe to drive because U0586 affects infotainment and navigation communication, not engine, braking, or steering systems. Avoid relying on the factory navigation for directions until the fault is repaired, and address any battery or charging issue promptly to prevent further network faults.
