OBD-II trouble code
U0463: Invalid Data Received From Navigation Display Module
A module is receiving messages from the navigation display module, but the data inside them is implausible or out of range. The link is alive; the content is wrong. It affects the navigation/display screen only; the car drives normally.

What does U0463 mean?
The navigation display module drives the screen that shows the map, route guidance, and often shared functions like the backup-camera image, audio menus, and vehicle settings. It talks constantly with the navigation control unit, the infotainment head unit, and the rest of the network so the right image and touch inputs flow both ways. U0463 sets when a receiving module is still hearing from the navigation display module, but the data in its messages is invalid — a value that's out of range, internally inconsistent, or in conflict with what other modules report. The connection itself is alive; the content simply can't be trusted, which is the defining difference from a lost-communication code, where the module goes completely silent.
This is an information/convenience fault, not a driveability fault. The engine, transmission, brakes, and steering are unaffected. What you may notice is the display acting up: a frozen or blank screen, garbled graphics, touch inputs that don't register, or the display restarting on its own. On vehicles where the same screen serves the backup camera, the camera image may also be affected — worth knowing before you reverse, even though the vehicle itself drives normally.
Causes follow the familiar invalid-data pattern: low system voltage or a poor ground that makes the module compute or transmit garbage; corroded, loose, or damaged connectors; chafed or damaged bus wiring corrupting messages in transit; software problems (a failed or interrupted update is a classic trigger on infotainment hardware); a replacement display that was never configured to the vehicle; and finally an internal module fault. Because infotainment modules are essentially computers, a simple reboot — a battery disconnect or the system's own reset procedure — sometimes clears a one-off glitch, but a code that keeps returning deserves real diagnosis.
Common causes
- Low system voltage, a weak battery, or a poor ground at the module
- Corroded, loose, or damaged connectors at the display module
- Chafed or damaged bus wiring corrupting messages in transit
- Failed or interrupted software update on the infotainment/display system
- Outdated, corrupted, or mismatched module software
- Navigation display module replaced without correct configuration/programming
- Aftermarket infotainment or accessory wiring interfering with the bus
- Internal navigation display module fault
Symptoms
- Navigation/infotainment screen frozen, blank, garbled, or rebooting
- Touch inputs not registering or behaving erratically
- Backup-camera image affected on vehicles that share the screen
- Companion infotainment or network-communication codes stored alongside U0463
- No change in how the vehicle starts, runs, or drives
Diagnostic steps
- 1.Read all stored codes and note any companion infotainment or network codes — a cluster of invalid-data codes points at a shared power, ground, or bus problem rather than the display itself.
- 2.Check for available software updates for the display/infotainment system and confirm any recent update completed successfully.
- 3.Perform the system's reset procedure (or a brief battery disconnect per the service manual) and see whether the fault returns.
- 4.Load-test the battery and verify charging voltage and the module's grounds.
- 5.Inspect the connectors at the display module for corrosion, looseness, and bent pins.
- 6.Check bus wiring to the module for chafing and damage, especially where harnesses pass through the dash.
- 7.If power, wiring, and software check out, suspect an internal display module fault and verify with service data before replacing.
Repair cost
$100 – $600
Cost depends on the cause. A software update or reset may be free to cheap. Repairing a connector, ground, or wiring fault typically runs $100-$300. Navigation display module replacement with programming is the higher end — commonly $300-$600 aftermarket or refurbished, though a new OEM display on some vehicles can exceed this range, so diagnose before replacing.

DIY vs shop
This is an intermediate DIY job. It usually involves diagnostic steps, specialty parts, and some careful work in tight spaces. If you have the tools and a service manual or trustworthy video for your specific vehicle, it is achievable in a weekend. Otherwise, a competent independent shop will be faster.
