Just got a reply call from my local service center regarding my service request for installation/enabling of PWS to allow for Boombox on my Model Y (June delivery, 137XX). The service advisor indicated that ALL Model Y’s have a version of PWS installed from the factory, however Boombox does not work on all (obviously). Apparently a retrofit is planned in the future (no date estimate), and nothing can be done at this time.
Hope that helps others trying to figure this out!
