Zumo User Forums

I recently acquired a 665, to serve as a backup to my 660. I use the 660 to listen to music while riding, and have about 1900 songs loaded. All of my MP3 files are located on the SD Card.
I have these MP3 files in a folder called "MUSIC" and then several subfolders under it. This works perfectly on the 660, and it finds all of my MP3 files.
However, the 665 won't find my music files. I have tried the following:
1) loaded MP3 file in the 'root' directory of the SD card
2) loaded MP3 files in "MUSIC" folder and then subfolders under it (copy of my 660 setup)
3) loaded MP3 files in folder named "MP3" just incase that's what the 665 required

on a whim, I created a folder called "MP3" in the internal memory and copied 2 MP3 files to that folder. Media Player sees those 2 files just fine, but will not see the files on the SD card. Any ideas?

Is the SDcard formatted as FAT32? A Zumo will not recognize any other format.

Yes the card is formatted as FAT32. After my original post, I
- reformatted the card (again as FAT32) not quick format
- connected the 665 to my PC and copied a set of MP3 files that way instead of with the card inserted into my PC.
(I didn't really think this would matter, but what the heck, I hadn't tried that yet)
Still the 995 does not see the MP3 files on the SD Card.

I connected the 665 to Garmin Express and noticed that the internal memory is reporting 97% full.
That caused me to look at the device in Windows file manager (or whatever it's called in Win10).
There are 375 MB of files in the "Voice" folder with names of numerous other languages ( Bulgarian, Chinese, etc).
Can these be deleted only keeping the couple that I might want to use (English_American_xxxx).
Same questions about files in the "Vehicle" folder, can I simply delete any I don't want to use?

Yes. You can delete any voice files for languages that you can't/don't want to listen to.

I always thought that music files had to be in a folder called MP3. And even calling it mp3 instead would cause the Garmin to not see them.

I can tell you the following. I have both a Zumo 550, 660 and a 665. On all of the units the "Music" files are stored in a folder on the SD Card named MP3. I just took a screen shot of the storage on the 665 and 660. Here is the shot. Cann't seem to post it as I expected.

Well I appear to have a solution. They mystery may not be completely 'solved', but I appear to have a working unit that now 'sees' my MP3 files.
I removed/replaced the 32Gb card with a 16Gb card and all of my music files are now recognized by the 665.
I have been using the same model 32Gb card in my 660 for several years, and assumed (yes I know what that equals) it would work in my 665 since I found numerous people on the web reporting success with a 32Gb card in a 665. Oh well, live and learn.
my 1901 song library easily fits on the 16Gb card so this will work just fine.
thanks to all who replied.

I recall reading a tip recommending that when formatting a 32GB card use a 32kb allocation unit. It wasn't made clear why this worked. Unfortunately, I don't recall the specific device that tip was for.

After reading the reply from Peobody, I checked, and I have another 32Gb card (different brand, ONN instead of the Samsung I've been using) that is formatted with 32kb allocation unit.
I loaded my music library onto it and gave it a try. Well the 665 reads it just fine. Now I'm wondering was it the 32kb vs 16kb format, or the brand of card. So I reformatted the Samsung with 32kb and loaded the music onto it. The 665 will NOT recognize that card. So there is something about a Samsung 32Gb "EVO Select" flash card the 665 doesn't like. I don't know what, and frankly at this point, I don't care. As far as I am concerned, Mystery Solved.
