Hi all, I recently purchased a 2016 E350 CPO and decided to load up some music on a MicroSD card, stuck it in an adapter...but the SD Card slot won't read the card and I keep getting the error "SD Card Unreadable"

I've tried multiple formats, from FAT32 to exFAT, but each time it doesn't appear to be able to read the card.

Does anyone have any ideas, I've already tried resetting COMAND (as suggested elsewhere on this forum) by holding down the power button for 10 seconds, but that didn't seem to help either.

I only have about 170 songs in M4A format on the card so far, but the error I'm getting indicates it isn't even getting that far.

Thanks again for the help.

Just try a new card. I have a 128GB one, formatted in exfat (I think) . Loaded up around 9500 songs and it worked for about a week and then started giving the same message. I reformatted and reloaded the songs and it's been running fine (and used daily) for the last 6 months. Cards are cheap enough to give another one a shot, just try and buy a decent quality one. Also, in my scenario, I don't have very deep filesystem trees, maybe 3-4 folders deep max.

Thanks, happened to have an old 2GB Kingston that I tried and it works fine. I'll spring for a higher capacity card soon. Thanks again!!
