On which aircraft is there a disabled MP3 player in place of the ABS?

The ERJ 175 is designed to accommodate various passenger comfort features, and in this case, it includes a disabled MP3 player as a substitute for the AVOD (Audio Video On Demand) system, typically referred to as ABS. This setup allows airlines to provide entertainment options while also addressing cost and operational considerations. The decision to disable the MP3 player may relate to the aircraft's entertainment system capabilities or specific airline configurations and policies.

In contrast, the other aircraft models, such as the ERJ 170, CRJ 900, and Boeing 737, either retain their AVOD systems or do not include this specific disabled MP3 player feature, which distinguishes the ERJ 175 in this context. Each aircraft model has unique configurations and amenities that cater to different operational needs, ultimately affecting the entertainment options available to passengers.
