Since my college days, I've always had a great collection of albums then CDs (which I still have in hand built custom cabinets) and I bought the best stereo system I could afford for playback of this music. When I would buy a new car, I always upgraded to the best stereo offered from the factory.
With my decision to really consider the 2025 Acura ADX, a YouTube thorough, positive, review of the Bang & Olufsen 15 speaker system available on the 2025 ADX A-Spec Advance confirmed the only version I would buy. In the video review, I paid close attention to the music source that was used in order to take full advantage of the system capabilities and then I began my research of what I needed to replicate the ability to "stretch the legs" on the B&O. After taking delivery of my ADX, I read the owner's manual and in the infotainment section, it discusses how to use the USB feature, specifically the proper format of the USB-c which is FAT16 or FAT32. I further researched the format and read about how exFAT is the newer version of format and it is supposed to be compatible with the FAT16 or FAT32 specified devices.
Another aspect of my research introduced to me a term I had not heard of before - Lossless Music. When I first saw this term, I was fascinated how I had not heard of lossless music before, which lead to more research to understand about lossless (and lossy) and what I needed to do to copy my music from CD to computer to USB flash drive for use in my ADX. Also, I discovered Apple Music has their own version of lossless music and how to properly adjust for lossless playback; Bluetooth will not support lossless format, you must plug in your iPhone for CarPlay into the USB port on the ADX for lossless music. I found a free program to use to copy my CDs in FLAC (Free Lossless Audio Copy) to wav so ALL data on the CD would be copied to the computer, thus no loss of music and also to import metadata to the computer to copy to the flash drive so it would be on the infotainment display of the ADX, identifying the song, the artist, the song, and the album, and album cover art.
Now, I have over 400 CDs and I decided to copy using the EAC program to copy my CDs to computer, which took a great deal of time to complete. After copying about 50 CDs, I couldn't wait to see how my project would work in my new ADX and how the sound would be on the B&O with 15 speakers including the rear subwoofer. I bought a new USB-c flash drive (64gb), formatted the flash drive to exFAT, which was the only choice I had on the format drop-down menu and uploaded the first of the music I had copied to the flash drive, plugged it into the USB-c port in the ADX and the message - Please Use a Compatible Device. I tried a couple different things in the vehicle to no avail.
I went to the Acura dealership to get help and the salesperson, the parts department nor the service department could offer any advice. I then went to Office Depot, where I bought the lash drive, and they could not offer any advice either. So, I went to Best Buy to get advice and the salesperson there could give no advice. I then went to a large independent stereo store here in Charlotte to see if I could possibly get some advice and the employee there could not advise me either. I got in my car to leave; then I had a thought and went back in the audio store and asked the employee if he had any way to plug in the flash drive to see if it had music on it. He said sure, plugged the flash drive in a stereo display, turned on a car stereo and the music on the flash drive sounded GREAT! What do I do now? Part Two - To be continued!
