U0463Invalid Data Received From Navigation Display Module
- Generic OBD-II code · Network
- How the car detects it
- The navigation display module is the screen part of a navigation head unit that shows maps and route guidance. U0463 marks invalid data from it, while U0162 means it is silent and U0464 concerns the navigation control unit. Subaru documents the partner: in bulletin 07-205-22 the rear vehicle detection module of the 2021 Crosstrek and 2020-22 Forester stores U0162 and lights its warning until reprogramming makes its CAN exchange with the head unit more robust, and TechTIPS 10/2015 calls the unit audio visual navigation display. No maker documents U0463 in this sense. FCA, now Stellantis, uses the number differently: in PCM bulletin 18-090-19 for the 2019 RAM ProMaster, U0463 is a fuel level plausibility code that new software switches off in favour of P0463. Usually only map and screen are affected; no MIL.
