Sync 3 Upgrade Failing

I am trying to upgrade my Sync 3 to 3.4 and it keeps failing. I get a message immediately that says Installation paused. “The USB storage device has been changed or removed. Installation will resume when the device is re-inserted”

I have tried two different USB drives and multiple versions of sync 3.4 with no success.

Full disclosure, there is a guy on a forum that installed a 32gb card into his non-nav sync 3 unit. Doing the same steps as if he had nav all along. i attempted to do the same thing. the card is currently on 2.2 and my was originally at 3.0.

Was there a solution, I am having the same issue.

I’m not sure if this will help but if you already got to the red reformat screen I read somewhere that fully turning the car off and back on again - i.e turning it off, getting out of the car, locking it, then unlocking it and turning it back on again and trying once more made it work

Use another USB specifically one without U3 smart or virtual CD drive emulation etc.

Hello! I am new to this website and I’m trying to update my Sync3 3.0 to 3.4. I used Syn3 Updater v2.0 to format my USB drive, but every time I insert the drive into my vehicle I get a pop up saying that “The USB storage device has been changed or removed. Installation will resume when the device has been re-inserted.”

This was the only feed I could find with this specific problem. I have tried using seven different USB drives, old and new, 2.0 and 3.0. I have tried resetting my Sync3, but nothing seems to be working. I currently have Sync3 3.0 Build 17276 and I can’t even get my car to update to the Ford released update of 19205. I am attaching a few pictures to show you, any help would be greatly appreciated.

My vehicle is a 2018 Ford EcoSport SE with version Sync 3 3.0 Build 17276, North America region, USA.

All the different USB drives I’ve tried using.

The last time this happened it was due to a faulty usb hub, cabling or similar. I’d recommend pulling out the hub and reseating all cables, and check there is nothing stuck in the port itself.

On top of that, if you have more than 1 USB port, make sure nothing else is connected to the other ports.

Yes for sure, it’s amazing how many people forget that they have like another USB drive inserted

I have one with two ports and I always make sure there’s nothing else connected. I’m able to connect my phone into both usb ports so I don’t understand why that would work but not the jump drive, but I’ll try pulling out the whole unit.

@FlightPhonic Did you ever find a solution? I am seeing this in my '18 Mustang Sync 3 with that same version that I can’t upgrade off of, 3.0 17276

Has this issue been resolved? I have nothing plugged into my USB ports except for the single USB, and I have tried to reseat connectors and clean ports out. Still popping up. Going from 3.0.17276 to latest.


Do you also not have anything in the SD card slot?

@CyanLabs nothing, i didnt even know i had an sd slot. I got it to where in indexes now but then pops up same message. To get to where i got it to index, i deleted the log and the DNTINDEX.msa files from the usb

DNTINDX means don’t index, you just took that option away… share your log
