Description: When the vehicle is started with a USB Device containing audio (e.g. music) plugged in, as Sync boots up and during its search for the last audio (device) that was playing when the vehicle was last turned off, the USB Device is sometimes not seen as ready and Sync then defaults to the Radio.
There are two USB data transfer ports in the ā21-ā24 Bronco Sport, USB-A and USB-C. Both ports are located below the 8ā Display.
I am not sure what USB Standard the Bronco Sport data transfer ports are. I am guessing the data transfer ports in the Bronco Sport are:
USB 2.0 - 480 MB / sec
The Owners Manual might state that information.

Bronco Sports running Sync 3.4.23188 or earlier versions⦠at the time this post was written 23188 was the latest version.
Make sure you are running SYNC 3, Software Version: 3.4 Build 23188 PRODUCT or latest version. If Customer Satisfaction Program (CSP) 24B47 applies to your VIN, make sure you have CSP 24B47 completed.
Some owners never have issues - the audio on their USB Devices always starts playing when the vehicle is started (after Sync boots up). Post #2, #8, #9, #11 at this link are examples of owners stating the USB Device always works: https://www.broncosportforum.com/forum/threads/sync-3-and-usb-stick.10224/post-177431
Other owners do have issues where the USB Device most of the time is not recognized and has to be manually selected as the audio source on almost all vehicle start ups. Like stated at these links:

I believe the root cause is a Sync software issue that is timing related.
Ford could insert a software delay to allow more time on startup for the USB Device to be ready but that would then add an unnecessary delay for owners that donāt use audio USB Devices.
Why do some owners never have an issue playing audio from their USB Device and some owners see their USB Device is not always selected as the audio source on startup and has to be manually selected?
Letās look at what may influence a USB Device from being selected:
1. The APIM (which is the module where Sync runs) - the Sync software might run faster on some owners vehicles. This could be due to a variety of reasons such as what Apps are selected, how much free memory is available, etc.
2. Sync is reported to support up to a max size USB Device which may be 128Gb (see Post #12 at https://www.broncosportforum.com/forum/threads/sync-3-and-usb-stick.10224/post-177468) however at least one owner reported using a 512Gb USB Device and had no issues, Post #16: https://www.broncosportforum.com/forum/threads/sync-3-and-usb-stick.10224/post-177559
3. Some owners might be using a faster USB Device for their audio than other owners use. USB Devices have a variety of specs which may influence this:
- USB-C vs. USB-A Devices (typically USB-C Devices are faster)
- USB Device Read/Write speed spec: in this case the Read speed is important
- How long it takes the USB Device on power up to become ready (I donāt know that there is a spec for this)
4. I am guessing the Folder layout and number of audio files on the USB Device could influence the USB Device timing to become ready (I recall seeing articles on that topic).
5. I am guessing the types of audio file formats (e.g. WMA, MP3) could influence the USB Device timing to become ready (I recall seeing articles on that topic as well).
6. I am guessing the USB device memory size (in Gb) could influence the USB Device timing to become ready (I recall seeing articles on that topic as well).
Possible solution:
A faster USB-C Device (faster Read speed spec) may solve the issue where the USB Device is sometimes not selected as the audio source when the vehicle is started.
My recommendation is to obtain a fast USB-C 32Gb max device (keep in mind the speed supported by the Sync software and the Bronco Sport USB-C data transfer port likely is the limiting factor). Then properly format the USB-C device (FAT32 format for music files*) and initially store no more than 100 audio files total all in a single folder. Use this for a few weeks and see if the device is always selected as the audio source upon vehicle start up where the USB Device was playing last when the vehicle was last shut down. Why 32Gb max when 128Gb or even 512Gb is max that Sync might support? No reason other than some owners with 32Gb size device report no issues.
*(however other owners state they format as NTFS and works fine)
If the issue disappears, then store your usual number of audio files organized with your desired folder structure and test with that for a few weeks.
Please keep in mind this issue may have no solution. Youāll have to decide how much effort (and money) you want to invest on this.
