Preparation
・Tesla software must support Boombox (Holiday Update or later)
・Put the Tesla in P (Park) — only works while stopped
・Pedestrian Warning Sound (PWS) must be enabled for your country/vehicle
・⚠ If you use an iPhone as the Boombox performer, the conductor should use a separate device (running "auto calibration" on the same iPhone makes iOS lock the Bluetooth profile to HFP call mode; it may not return to A2DP even after Bluetooth OFF/ON or Safari restart, and Tesla's "Play current media" may stop responding. Using a different device — Android or another iPhone — as the conductor avoids this)
Steps
① Connect the phone to the Tesla via Bluetooth and set the media output to the Tesla
② On the Tesla touchscreen, open Toybox → Boombox
③ In Boombox, enable external speaker output from the "Play external when honking" or "Custom sound" section (follow the in-car UI)
④ Turn ON "Use external speakers" on the Boombox screen
⑤ On this performer screen (phone), wait for the timer or the conductor's play command
⑥ Phone audio flows to the Tesla via Bluetooth and plays through the external speaker
Notes
・Do not close the phone screen during play (no sleep / no lock). When the screen turns off, the browser pauses playback and timing drifts. Set auto-lock to a long interval (or off) and keep it on charge if needed
・External speaker output is disabled automatically while driving (out of P)
・Adjust volume from the Tesla's media volume
・UI names may differ depending on model / year / software update
