Strange NBT Evo USB problem. - ccfj1 - 08-29-2025

Hi All,

As above, I have a strange NBT Evo USB problem.

Its a bench setup (nbt evo, zgw, jbbr and kombi), have also a homemade EGS emulator and volume controller.

I have both USB enabled as per the 1000's post online, (with all codecs enabled), however with any media usb I plug in sees the USB and all songs/video, playlists etc I can search the media and select all tracks playlists, albums etc. once I select them, they refuse to play, (time display stays on 0.00).

I plug an ipod in and both ports work perfectly.

Plug a map update and again both ports work.

Same USB sticks and ssd work perfectly in my car (nbt evo retrofit), so not a media formatting problem.

The only way that it seems to work (not 100%), is if I power the unit and on first time see usb.

I select the usb port with music on and then power nbt off, power unit back on and then the nbt powers on and selects the USB, it then loads media and then for some reason, starts playing... if i then select aother track in same auto select (first on media) album, then that works, if however I select another playlist again stops working.

If I select any other media source (ipod, radio, dab, tv, spotify etc), USB stops working and wont restart playing.

Ive tried multiple codings of USB ports and spent a lot of time looking online.

I really don't know what to do next, I need this working on the bench as I'm planning to retrofit into a mates e46 (with homemade i-bus->canbus emulator), I have the emulator built and im testing but can't deploy until all nbt evo features work on the bench, id6, atm/gps, phone, carplay spotify, all working perfetcly,  just this stupid USB problem.

As you can imagine Ive tried every thing I can think of and 100's if different coding options.

Any one have any ideas.
