2025 Nautilus - No Aux Input Via USB-A?

[swindler]

Very interesting. Can you tell any difference in the replacement from Samsung? Different formatting? I can't get any of my 4GB sticks formatted FAT32 to be recognized.

Have you tried a low-level format vs quick format? Have you tried MBR vs GPT? You can change that if you use the Disk Management utility.

All the flash drives I've tried have worked. As such, I've never had to experiment. I'm not sure what else could be your difficulty.

There's a sliding door that closes?

Has anyone found out how to make the music files on the USB stick play in the order you want them to? Play all seems to play them in alphabetical order by meta data song title. If you select album it only plays one album and does not continue to the next one.

I heard a while back it was alphabetical via filenames. But I can't confirm this. A suggestion was given to use the utility MP3TAG to set the order of files with a numeric prefix, but I honestly haven't explored this. Good luck.

There was no difference. Also, the first USB did work in my Nautilus, with time, it stopped working on occasion, then more and more. I'm so used to electronics never failing, but I think in this case the drive did fail.

Yeah, I knew. But neither my wife nor I ever close these things on our vehicles. They might as well not exist. Not that we're messy. We're just utility-driven.

No, If it was alphabetical by file name it would do what I want, since I have named all of my 4500 files Album name- Artist- track number- song name. If someone could tell me the playlist format and the playlist file format I could make a playlist that play songs in the order that I like.

I believe it works off of the ID3v2.3 tags, not the filenames. I generated a couple set of files to try testing, haven't gotten around to it yet (modifying the tag Track and Title tag fields on 3 copies of the same album mp3 files).

Form does follows function, iff the function is not impeded by form. How difficult was it to remove your glove box door?

I just knew someone would go there. It wasn't too bad, but everything kept falling out when my wife would peel tires trying to always be first racing from the stop lights. I had to put it back on.

I've tried various different USB sticks - 2GB, 4GB, 256GB, all formatted FAT32, some completely reformatted, some with folder, some with drive name, etc. etc. etc. and the only ones that work are 2GB. I'm gonna chalk this one up to 2025 non-hybrid Nautilus software.

This low profile thumb drive allows the sliding door to close and works well in my USB A port. I use it mostly for listening to books rather than music as Spotify has most of my music available.

Hi
I also have a 2025 Nautilus Reserve.
The USB stick needs to be formatted with FAT32 or exFat
I had a 2017 Lincoln MKX that worked fine with a NTFS formatted USB stick.
After reformatting & coping all my music on to the USB stick, the Nautilus will play detect & the songs.
HOWEVER...SYNC 5 has so many issues playing mp3 songs from the USB stick that I am thinking of just using Spotify.
It works until you shut off the vehicle, then the next time you start it, it won't play or it won't even recognize the drive.
It corrupts the USB stick & it needs to be repaired by plugging in into a PC * going thru the repair process.
Then it will work again until the next time you shut off the vehicle & the process repeats....

On our '25 R2, AudioWagon works consistently with a 256GB USB drive formatted to MBR FAT32, using the default cluster size Rufus recommends. The one glitch is that it doesn't persist (retain) the permission to access the USB drive across restarts (it'll last for a little while, until all the computers have truly shut down). Each time I start the car I need to give it permission again.

There's a bug in Lincoln's implementation of something called car-usb-handler. car-usb-handler is part of Google's AAOS, what the infotainment system runs with relative to music. When the user clicks the little checkbox in a popup, and says to allow access, Lincoln should be saving that setting, then checking for it on the next start, but they don't.

I believe the same issue applies to the '24 Nautilus and, I expect, the '26.

People need to complain to get it on Lincoln's radar, so they fix it. Log a call with Concierge, use the new voice-message functionality to let them know, send a carrier pigeon with a message.

I'd call it "functionality not working as it should, a warranty issue", as the documentation states the vehicle can be used to play music from a USB. AudioWagon, best I can tell, is the ONLY real USB music player (with full library/catalog capability, properly responsive to voice commands) offered on the vehicle's Play Store, and they document that Lincoln has a bad implementation in their FAQs.

It definitely wants to see MBR FAT32, not GPT. I played with that recently just to confirm. Same USB, same Rufus settings except switching between MBR and GPT. MBR worked fine, GPT not at all.

On the plus side, while checking things on the Nautilus I found out that our '17 RX350 can also work fine with a 256GB USB, formatted as MBR FAT32, though it has a 9,999 total songs limit. I'll have to strip some things to meet that (I had been running a 64GB in the RX - that was the maximum stipulated in posts on multiple Lexus forums, for years).
