How do you update?Mine works great now that I updated to the latest Sync 3 release. The previous release worked for 2 years then got flaky. I run all .m4a files on a 32 gig exfat format.
Normally you get the Sync update here:How do you update?
Nothing has worked so far. I copied everything to a 128gb drive formatted Exfat with no change. I am using an Ottocast wireless adapter which may be creating some conflict but tried it without the Ottocast and it still does not work. Next step will be to use a 32gb drive with two or three music files and see if that works. I do have a lot of apps that run on Carplay.@kshaw … did you get a chance to try any of the suggestions throughout this post (e.g. Post #14) and now your have your USB Device music working?
Even thought Ford has a documented recommendation of 128MB max USB Device, I think that may have more to do with the USB size that works across any of Ford’s Sync3 Hardware (for example, APIM in Bronco Sports) … some of Fords Sync3 vehicles have less memory in the module that runs Sync3.
As you see from others posts, even a 512GB SanDisk Ultra Fit USB-A formatted NTFS (356 GB used with 9400 FLAC files) works in a Bronco Sport with no issue.
Another thing that sucks up memory in the APIM is what Apps are run, for example both CarPlay and Android Auto take up available memory - so owners with 256MB and 512MB USB Devices could be running with less Apps.
Ford’s recommended 128MB may be conservative to account for several variables.
But at least you can see that a USB Device containing music up to 512MB can work in a Bronco Sport.
The September update has been installed..We still have no idea what build number of Sync 3.4 you are on.
Can you post the build number?
That’s great, I corrected my list of possible fixes for a music USB Device that stops working. Here’s the updated list that typically will workIt is working now! I reformatted my Sandisk with 256gb to NTFS and the USB is now recognized and working well.
