OBD-II trouble code
U0464: Invalid Data Received From Navigation Control Module
A module is receiving messages from the navigation control module, but the data — position, route, or guidance information — is implausible or out of range. The link is alive; the content is wrong. Navigation may misbehave; the car drives normally.

What does U0464 mean?
The navigation control module is the brain of the navigation system: it processes GPS position, dead-reckoning inputs like wheel speed and yaw, and the map database to compute where the vehicle is and how to route it. It shares that information over the network with the display, the instrument cluster (for turn-by-turn prompts), and sometimes driver-assistance features that use map data, such as speed-limit display or predictive cruise. U0464 sets when a receiving module is still hearing from the navigation control module, but the data in its messages is invalid — a position, heading, or guidance value that's out of range or in conflict with what other modules report. The link is alive; the content can't be trusted, which distinguishes this from a lost-communication code where the module goes silent.
This is a convenience/information fault. The engine, transmission, brakes, and steering are unaffected, and the vehicle drives normally. What suffers is navigation: the position may jump or lag, the vehicle icon may drift off the road on the map, guidance may be wrong or absent, or map-based assistance features may temporarily disable themselves. Because the navigation module fuses GPS with vehicle sensor data, bad inputs can be upstream of it — a wheel-speed or yaw signal problem, or a GPS antenna fault, can make the module's output look implausible to the rest of the network.
Causes follow the invalid-data pattern: low system voltage or a poor ground; corroded, loose, or damaged connectors; chafed bus wiring corrupting messages; a faulty or disconnected GPS antenna feeding the module garbage; corrupted map data or a failed software update; a replacement module never configured to the vehicle; and an internal module fault. Software and antenna issues are disproportionately common on this code, so they're worth checking before any hardware gets replaced.
Common causes
- Corrupted map data or a failed/interrupted navigation software update
- Faulty, loose, or disconnected GPS antenna or antenna cable
- Low system voltage, a weak battery, or a poor ground at the module
- Corroded, loose, or damaged connectors at the module
- Chafed or damaged bus wiring corrupting messages in transit
- Bad upstream sensor inputs (wheel speed, yaw) used for dead reckoning
- Navigation control module replaced without correct configuration/programming
- Internal navigation control module fault
Symptoms
- Vehicle position jumping, lagging, or drifting off the road on the map
- Route guidance wrong, delayed, or unavailable
- Map-based assistance features (speed-limit display, predictive cruise) temporarily disabled
- Companion infotainment or network-communication codes stored alongside U0464
- No change in how the vehicle starts, runs, or drives
Diagnostic steps
- 1.Read all stored codes and note companions — display, infotainment, or wheel-speed/yaw sensor codes can point at the true cause.
- 2.Check for navigation software and map updates, and confirm any recent update completed successfully.
- 3.Test GPS reception in an open area; poor or absent reception points at the antenna or its cable.
- 4.Load-test the battery and verify charging voltage and the module's grounds.
- 5.Inspect the connectors at the navigation control module for corrosion, looseness, and bent pins.
- 6.Check bus wiring to the module for chafing and damage.
- 7.If software, antenna, power, and wiring check out, suspect an internal module fault and verify with service data before replacing.
Repair cost
$100 – $800
Cost depends on the cause. Software/map updates are often free to modest. A GPS antenna or cable repair typically runs $80-$250. Repairing a connector, ground, or wiring fault runs $100-$300. Navigation control unit replacement with programming is the top end — commonly $400-$800, and new OEM units on some vehicles can cost more, so exhaust the cheaper causes first.

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.
