Lexus IS350 intermittent navigation screen issue unresolved for over a year on Lexus IS350

Some Lexus IS350 owners report experiencing intermittent navigation screen issues that have persisted for over a year, indicating a potential manufacturer-wide problem. Many have identified that the issue may arise from a faulty connector on the touch panel or problems with the display itself. In cases where the navigation screen appears completely white yet remains responsive to touch, it suggests a display malfunction rather than a total system failure. Additionally, some owners have encountered a black screen after a battery replacement, which may point to an electrical issue. Missing GPS indicators or consistently incorrect location readings could indicate calibration or GPS signal problems. Some users have found success in resolving these issues through DIY methods such as recalibrating the navigation system or replacing the display driver board. For those seeking a more permanent solution, options like purchasing a new screen or a complete navigation system replacement are available. Given the complexity of these issues, consulting a professional technician or Lexus dealership is advisable for a proper diagnosis and resolution.
