Inserted a flash drive into the glove box USB port for the first time which has 2 MP3 tracks on it. When I selected USB in command it tried to activate but then after a few seconds came up with a "device not compatible" message. Is there another step I am missing

 

The files need to be on the root of the drive and the drive should have nothing else on it. Format it FAT32 and then load the files directly onto the root of the drive (no "music" sub folder or anything)

I believe it wants MP3 only, not AAC etc. Your iTunes library (if you use one) will be AAC but can easily be converted. I have a full tutorial floating around here somewhere.

 

Hey Mike--I have some 7000 tracks in folders and nested sub-folders on my USB device and it works fine both in the glovebox as USB and console as SD.

Things I have noticed:
The system will read MP3 (CBR/VBR) and WMA
It does not support >32GB partitions (and the partition has to be active)
It does not like some USB3 devices

I would reformat the device as FAT32, make sure it is not larger than 32GBs and try again.

 

Good stuff. I always forget that WMA exists. So do you have a master Music folder and then sub folders by Artist? I couldn't get mine to work that way. Might have been a partition problem.

 

I have about 30 folders off of the root, and many sub-folders beneath that. Yes, they are organized by artists, albums, and others.

The most reliable setup I found was using a USB2 device (or MicroSD w/ a USB2 reader), format it as a single <32GB FAT32. If the memory is natively more than 32GBs, make sure it is the primary active partition.

The Benz plays 320kbps MP3 fine (wish it supported FLAC, but I think it would be the point of diminishing returns).
