Has anyone experienced problems with the audio system? Occasionally it stops advancing to the next song on my USB drive unless I do it manually. Shutting off the car and starting up again appears to clear this up.

Also noticed today I was unable to go from USB to FM radio until I shut off the car and restarted.

Hi Mark, welcome to the forum!

I have had the same issue on whilst using the USB. I always thought it was the USB that was acting funny - maybe there was a stock file or component of the USB that was in the way and kept the it from advancing to the next track.

If anyone has recommendations, I too would be curious to hear.

Hi

The USB playback has some issues....not just a CX3 thing but all Mazdas with the MZD Connect entertainment systems.

USB Playback from flash drive is slow as it builds a memory index of all files on the drive in the background then displays things like playlists, by artist etc etc. that it has created with reference to the GraceNote Music database that is resident in unit.

I have tested it with 64g drives with 48g of music in a proper structure etc and it all works, but takes many minutes to have music navigation other than by folder and can get confused on occasion. needing a reboot of unit or removal of card.

USB Playback from apple device is a fair bit more reliable (probably android as well but i don't have any to test).

The player seems to provide part of the effort in creation of lists etc etc but if you have a large library the system seems to transfer the lists to memory from the device.(Then creates the by alphabet navigation on screen). Way faster and more reliable than flash drives but still can get confused on occasion.

Also when you re start the car the playback will start faster from an iPod etc than a flash drive.

USB playback from my Android (Samsung Galaxy S5) appears flawless so far.
The same music set played via Bluetooth lacks volume, but when connected through USB it's great.:cool:

I had this problem with Bluetooth too with buffering depending on which device you used. I found using an iPod the Bluetooth connection was patchy but when I connected my iPad the playback was flawless. Mind you my iPod is about 5 years old so maybe that was more an issue but I won't know unless I buy a newer version.

For those of you with Android phones that are having trouble with BT volume, have you tried increasing the volume from the phone while music is playing and the phone is connected via BT? Android phones have several different volume settings, those conditions will trigger the right one to change with your volume buttons. My wife and I both have had no problems with BT volume from out Droid Turbos, but we do get occasional stuttering that is only solved by shutting off the car and restarting it.

I am new to this forum, I just got my CX3 on Wednesday so I am still learning about everything. My first issue I have run into is the stereo acting oddly with the USB drive. I first plugged it in and after the initial load it started playing the first song. I put it on shuffle and everything seemed fine as it picked songs from different folders when the song was finished. That was firs started this morning and it continued to work around lunch time when I next drove it. When I next drove today the stereo system seemed to reboot and started with a whole new song and then stayed in the same album folder shuffling songs. Has anyone else had this happen and does anyone now how to created playlists for the system to use?

I have all my music in a folder titled "Music" on a mini SD card which is plugged into a USB adaptor. It took no time at all to appear on the display arranged hierarchically under Artist, Song, Album, Genre etc. It has worked flawlessly for me for several weeks, changes music on the go and needs no intervention from me. I am very pleased with this arrangement. Someone else on here also gets good results from just copying the entire iTunes folder on the computer to a thumb drive. I guess you just need to experiment until you hit on something that works the way you want it to.

I have a USB drive plugged in with about 10GB of music on it.
So far it has stayed in the same folder it was in when I stopped the car with the either shuffle on or off (depending on what it was when I stopped the enginge).
What software version is Your infotainment on?
The only issue I've had, is the navigation not laoding the map. Which solves it self when I turn of the engine and turn it on again.

I would guess that many of the problems with the USB playback may be related to older versions of the infotainment system.

However, it's possible that some could be related to the USB flash drive itself. I work in IT and we use USB flash drives for system imaging. There are vast differences in performance between drives and they are not limited to USB 2.0 vs USB 3.0. I have USB 3.0 drives that are slower than the better USB 2.0 ones. We've also come across certain makes and models with poor compatibility.

Would it be possible for those people who's USB playback is working properly to list the Make and Model of the flash drive they are using, as well as the file system that it's formatted with, and the folder structure that they are using.

Perhaps we can use this to build up a list of recommended USB flash drives and a guide on how to format them and arrange your music.

Is there any way we could format the USB in the infotainment itself? I am just thinking it will help with the indexing of the music files since the usb is formatted in the infotainment and will make the usb playback run properly.

I think USB works but the more music u have the slower it gets.

I have just under 50gig on usb and while it is slower to initialise than an iPod or radio etc it takes a fair while to build the artist album structure etc.

An iPod with 50 g still does not start as quick as radio etc but is way quicker to get get to things.

For large amounts of music on usb folder mode is about the best option, playlists etc etc are too slow.

There is also a limit to # of files in a directory.

Go read the Mazda 3 forums and u want to understand why.

Geezer and Santa, thanks for the info. It turns out I had mistakenly taken the shuffle off and when looking at it again I was wrong in thinking how the icon should look when on. Anyway, that part is fixed now. I checked my infotainment version which is 55(I don't remember the rest of the numbers). Does anyone know what the largest size drive the system will recognize and also if USB 3.0 makes a difference?

The system works with usb 3.0 for playback, just not supported for firmware upgrades.

I have a 64gig usb 3.0 stick that is read fine.

For the most part my USB playback has been just fine over that last few days but it did stop on one song after it had switched to it. I just had to hit pause and then play for it to start. The one thing that my stereo seems to randomly like to do is restart from the beginning when I start my CX3 unless I had paused the currently playing song when I turned it off. When it does start over it plays the first song in the list but then with shuffle on it goes in the same order as in picks the same songs in the same order at least with the first three so far. Anyone else have this happen?
