Before we dive into the “how,” it’s crucial to understand the “why.” Firmware is the low-level software that controls the hardware inside your BDS 570. Harman Kardon released several updates over the unit’s lifespan. If you’ve never updated yours, you are likely missing out on critical fixes.

Further action

The most common complaint among BDS 570 owners is the dreaded “Disc Read Error.” Over time, the laser mechanism’s firmware algorithms become less efficient at decoding newer disc pressings. A firmware update refines the disc recognition table, allowing the unit to play DVDs and CDs that previously stalled or failed entirely.
