Audio System Crash - USB Flash Drive

[Shockwavesix]

Hello. Have a 2012 Edge Limited.

 

An ongoing issue for a while has been that about 1/4 of the time when starting the car, it would decide to reindex my Flash Drive of MP3's, and whatever else the audio system had been doing when the car was last turned off, it would switch and start playing the alphabetically first track on the flash drive. That was annoying, but I could live with it.

 

Starting yesterday, the car won't play my flash drive at all. Radio works fine, but with any attempt to switch to the USB device, it says that its Indexing, then after a second it just goes blank and says that there are zero tracks.

 

The car has been turned on and off several times with no change in behavior. I've reseated the flash drive, and tried the other USB port. The drive functions normally when connected to a computer. I've copied all my music off the flash drive and formatted it, then copied all my music back, and the car still won't read it.

 

Interestingly, when I formatted the flash drive I also changed the volume label. When I insert the flash drive back into the car, the car still says that its indexing, but it shows the old pre-format name. for that matter, when I remove the flash drive entirely and then try to switch audio inputs, the car still thinks that the old volume name is connected.

 

Anything I can try? I found an option in the settings to manually reindex, but that didn't help. I'm not eager to disconnect the battery and have to set everything els up again from scratch.

 

Thanks.

I corrected the issue by disconnecting the battery and forcing a hard reset... But then a week later it did the same thing again. Twice in a couple weeks after being fine for 3+ years. Something is obviously going on, but I don't know what. Needless to say, its annoying.
