What Does U0464 Mean?
The vehicle network is receiving invalid or corrupted data from the Navigation Control Module. This communication fault affects navigation system functionality and coordination with other vehicle systems that rely on position and route data.
Common Causes
35%
Faulty Navigation Control Module with internal processor or memory failure
25%
GPS antenna malfunction or poor signal reception causing invalid position data
20%
Corroded or damaged wiring between navigation control module and vehicle network
10%
Outdated navigation software or corrupted map database causing data processing errors
10%
CAN bus or multimedia network communication issues affecting data quality
Diagnostic Steps
1
Step 1: Use scan tool to monitor navigation control module data and identify which parameters are invalid (GPS coordinates, speed, heading, etc.)
2
Step 2: Check GPS antenna location for obstructions and verify antenna is properly mounted with clear sky view
3
Step 3: Test GPS antenna and cable for proper resistance and continuity per manufacturer specifications
4
Step 4: Inspect navigation control module connector and wiring for corrosion, damage, or loose connections
5
Step 5: Perform software update on navigation control module if available; replace module if invalid data persists after update and wiring tests good
Estimated Repair Cost
$150 - $1,800
Parts + labor, varies by vehicle and location
The vehicle network is receiving invalid or corrupted data from the Navigation Control Module. This communication fault affects navigation system functionality and coordination with other vehicle systems that rely on position and route data.
The most common cause of U0464 (Invalid Data Received From Navigation Control Module) is: Faulty Navigation Control Module with internal processor or memory failure
Typical repair costs for U0464 range from $150 to $1,800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
No direct safety concern for basic vehicle operation. Navigation system will be inoperative or provide incorrect routing information. Some vehicles may lose adaptive features that depend on GPS data.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U0464 to identify the root cause.
