So I have been having some issues in my 2017 Lancer ES with Bluetooth streaming to my radio where it will sometimes freak out and begin displaying question marks instead of the audio information. I have been unable to play audio from my phone (iPhone X) over the USB in my lower center console I searched around a little bit and decided to update FUSE as there were some prior forum posts I had come across about USB playback from iOS devices and Bluetooth stability. I prepared the USB and plugged in, the car recognized it after a few seconds and I went into the HFM menu to start the update and was met with "S/W Version: 50.00.000" as-well as the "S/W" button used to initiate the update being greyed out. I searched around a little bit and couldn't seem to find this issue occurring anywhere else. Has anyone else had this issue, and/or knows how to solve it?

 

I have the same problem and I didn't find how to resolve this issue
