What does “Software update install failed” mean on Subaru Car Navigation system?
- Mmatthew02Aug 14, 2025
If your Subaru Car Navigation system displays “Software update install failed”, it means the system software has been corrupted. The system will restart every 180 seconds. Turn the ignition switch to the “LOCK”/“OFF” position, open and close the driver’s side door, and ensure the system is off. Note that if any door remains open when the ignition switch is turned to the “LOCK”/“OFF” position, the system may not turn off.
