As it turns out, the Raspberry Pi Zero has a “USB gadget mode” that allows you to radically enhance the songs available to you on your car infotainment system — if you have the right plan. Here’s more from vanheusden:
My car (Opel Astra tourer) has a radio (the “infotainment system”) with a USB connector. You can put an USB device in it and it can then play the MP3 files on it. Really nice but there’s a catch though: the car radio has a 1000 songs limit. This sounds like a lot but after a few weeks they start to repeat and that gets annoying. Of course I could manually swap the USB stick but “oh the hassle”.
I read that the Raspberry Pi Zero has a “USB gadget mode”. This mode allows it to pretend it is a device of some kind (webcam, Ethernet adapter, etc). One of the devices it can emulate is a storage device like a regular USB stick!
