Requires a .wav under 1 MB and a USB drive. Used as the ASS / Smart Summon arrival sound.

1. 1
   Download the chime file. It saves as ASSChime.wav — already named exactly how Tesla expects it.
2. 2
   No reformatting needed — you can reuse the USB drive that came with the car for the dashcam. Just unplug it.
3. 3
   Place ASSChime.wav directly at the USB root — do not put it inside any subfolder (not in TeslaCam, Boombox, etc.).
4. 4
   Plug the USB into the glovebox data port.
5. 5
   Go to Controls → Autopilot → Customize Summon (or the Summon tab in the app) and set Completion Sound to your custom USB sound.
