I didn't start out looking for a boombox problem, but . . . . .
I wanted a flash drive with a few thousand songs on it, so I could listen to my choice in music at the given moment. Oops, there is only 1 USB port that is actually usable for anything other than charging. That one is in the glove box, and is primarily for dashcam. Best not to tamper with that one and screw up the car warranty or something. But found on the forum a link to a USB hub, which sounded like it would work with the dashcam and allow me to add other USB device(s). Got one, pulled the Tesla flash memory, plugged in the hub, plugged the Tesla flash memory into the hub, crossed fingers and began testing.
Works like a champ, my MY didn't care that the hub was in the mix. Formatted my USB flash memory and plugged it in. Everything still works. Copied 50,000 songs (mp3s), into 40 or so folders to my device and plugged it in. USB is now a valid source, I can choose folder mode and there's all my folders. Choose one, select a title and voilà, not only plays, but sounds really good. Have really enjoyed it for a couple of months.
Decided to try annoying the neighbors with my music choices. . . .
Tried to access boom box ... finally gave up and tried voice command boombox and it came to life and began to make noise. Actually, the rice crispy noise? Could control the volume, so it must be just a source issue? Did a forum search for boom box and got an insane amount of hits and spent a couple hours reading / scanning without finding anything that I could use to solve my problem.
Went searching for boom box sources on the car display and fumbled around for 1/2 hour or so and all at once - the neighbors were treated to Jerry Reed, Mule Skinner Blues. Let him finish, got out of the car to take bows and of course, when the door closed all went quiet.
Twas great fun, but since then I have been totally unsuccessful at ever finding the display path, button combination to ever achieve it again. While I'm waiting for my kid at Walmart and people gather around to ask Tesla questions and visit, I would really like to discover the magic and memorize the path to get back to it. In case anyone happens to have this function down cold. TIA
