Subaru WRX head unit erases saved radio presets randomly, requires dealership software update on Subaru WRX

Some Subaru WRX owners report experiencing issues with their head units, including random erasure of saved radio presets, freezing, and self-changing stations, which can be quite frustrating. Additionally, some users have noted that their radio presets are erased after just a few days, even without any battery disconnection, as observed in models like the 2019 Subaru Forester Sport. This problem also affects newer vehicles, such as the 2021 Outback Touring, where selecting a radio station can lead to the erasure of previously displayed presets. In some instances, the head unit may crash frequently, causing disruptions like repeated disconnections from Android Auto. Furthermore, while applying the latest software updates is often recommended, it does not always resolve these issues, and regular diagnostic procedures are suggested before attempting updates. Some owners have expressed frustration over the inability to easily delete preset stations, often seeking guidance from manuals and online resources. Given these persistent problems, affected Subaru owners may want to consult their dealership for assistance with software updates or further diagnostics.
