Given that i found such a compact (and cheap!) solution from china (Aliexpress) it might even be possible to fit everything in one box. Or that could be another dongle for whoever wants it.

Or f.e. this project. From what i found it would cost ~10€ in parts + the PCB + data "extractor" from USB. And, of course, software production. I can't comment on the coding part, because I've no experience, but from what i can see the device decodes any format of mp3 data and converts it to analog L/R output AND it can be controlled through some I2C protocol (hard/easy?).

So an additional 7-8 pin connector, maybe a dongle/maybe a small PCB in the same box with some cheap hardware, software for selecting input source and controlling the new parts, and....?

Also, I've been looking at the RN52 datasheet - I don't believe it outputs balanced audio signal to the IHU. They use something called "differential signals" and I'm not sure those two are the same. Extract from Wiki says it can run on single end signals, if done right. If I'm right that makes thing a bit easier, because of more existing decoding and converting solutions. Or an adapter can always be built, but it costs money.

As for the "visible in the trunk" part - I, personally, can't see any problem about sticking a 64GB USB stick, full of music, and throwing the whole thing behind some panels (or, as I drive a wagon, most probably in the side compartment). I don't imagine I could listen through all the music in a year :D
