Hi,

Anyone know how to clear the device file cache on the standard 2015 Mini MP3 Audio player???

Every time I plug in my Samsung Galaxy S6 into the USB slot it recognises the device but it pulls up a cached (in memory) file structure and so it doesn't recognise any new music that I have added.

Would appreciate some help if possible.

Thanks

Pumpkin.

Are you sure you are going via the usb input; if so i think this is a fault with your phone, rather than the car as i didnt think the usb port cached anything UNLESS you have the hard drive and are importing files? Have a check!

Yeah, its USB (in my car) to micro USB (in my phone).

I took my phone out and plugged in my GF's phone for the first time and after 30 seconds or so it displayed her files and file structure. I then put my phone back in and it once again reflected a cached version of my file structure and files (from the first time I ever used it).

I have over 30 albums on my phone and it still shows the original 4 albums (all of which no longer exist) in the menu.

I am sure it alludes to 'Memory' or similar in the car's manual which is why I think it has cached the file information from the first time the phone was connected. I believe it does this for quickness as would take 30 seconds to read and display this info every time you plugged the phone into the USB port.

Hopefully there is a way to reset this memory although I can't seem to find it.

Have you checked the structure on another device such as a PC? There is no caching of media through USB, the only memory it uses is the internal HDD when you copy music too it, you sure its not looking at that? double check by going all the way back to the media screen and select external devices, USB should have no value, then plug in your phone. The manual for the media/music is integrated in to the CBT unit its not in the owners manual :)

While there is no mention in any BMW user manual of this behavior, t is clearly caching the files structure, and search criteria such as artist, album and genre when you insert a flash drive. And just to be absolutely clear I am not referring to importing anything from a CD or anywhere else. This is exclusively with using the a flashdrive.

A simple experiment proves it. Place about 1000 tracks on the USB. When you first insert it, you will notice no or just a few artists appear in the search list for artists. After a while more appear. Now remove the USB. The reinsert it and search for an artist. Notice all are there immediately.

Then to further the proof, add the track of yet another artist, and insert it in the USB. It will take a while for the artist to appear.

As far as clearing the lost goes, I can find nothing on the subject. It seems to eventually get things right, but if you have enough track my experience is that it can take hours to straighten things out.

The one thing that may work is changing the volume name. I have done that one, but I am fearful of the consequences, such as filling up some cache area that we nor do our service techs no how to clear. I caution you not to get too clever. BMW support on the multimedia facility is beyond terrible. Even a simple question like how do you designate a track as part of an audiobook took 4 months to get a response.
