I purchased an M15 and was able to use it for a few weeks before I started having issues. As of 4 days ago, when my M15 is plugged in via USB to my vehicle, it will not complete Media Indexing and I can't do anything to bypass this. Here are the steps that I have taken to fix the issue with no success:
Reset Database
Upgraded firmware to 1.0.4 Upgraded Fiio Music App to 3.1.6 Tried a different M15 that worked without an issue Compared files and setting on a working M15 against mine Tried in a different vehicle (same issue) Tried a different Micro SD card tried without an SD card Reformatted Micro SD cards
Tried different USB cables I have opened a ticket (25477) with FiiO and they suggested this: "Are you using the car mode of M15: After turning on the car mode,
connect the M15 to the car USB, when the car is started, the M15 will
automatically start up and enter the driving mode playback interface,
and when the car is turned off, the M15 will automatically shut down. (Some
cars may experience large common ground interference after the USB is
connected to the M15. You can try to use it with the USB isolator LA-UA1
to solve it)." I am able to use a different M15 without using the LA-UA-1 without issue.
I am able to use Bluetooth connection to listen to music.
Any thoughts?
