My car audio system has only a USB Memory input without bluetooth(it does not have Bluetooth). The audio system is able to read the content of the USB memory, find the folders (MP3 files) and show them on the screen.
I was thinking to use a Raspberry Pi Zero W to setup it as both a Bluetooth Audio receiver and USB Mass Storage. Then writingwrite a program to write the bluetoothBluetooth audio as aan MP3 file into the mass storage space, and keep updating the MP3 file in the hope of the audio system of my car be able to open that MP3 file, show the metadata on the screen and play the MP3 audio.
Is such solution evereven possible with Raspberry Pi Zero W?
