I am looking for some help. I am trying to download the newer versions of software for my 2015 radio. I am attempting to 1.) go from the installed 1.19.2, to what the Boom! website says is the latest version of 1.20.1; as well as 2.) get the dealership updates. I found out I can't update the NAVI without $, so I have not attempted that one. I have downloaded the zip files for both updates (the radio took 1.5 hours!) and then dragged them to a 8GB thumb drive (which showed more than enough room), but when I put the ignition switch into accessories position, turn the radio on and plug in the thumb drive, the light on the thumb drive flashes, but the radio doesn't recognize the files, I guess. It shows "no playable media found" on the screen. Has anyone successfully done this upgrade?
