Hope this is the right forum. Not selling anything here, just gauging interest, and would be glad to talk about any of the technical details of it.
Still need to see what models/years this would apply to, but my '04 LX 470 has a tape player, but no 3.5 mm connection.
It's easy enough to inject audio into the tape player and just keep a tape inserted to trick it into playing. Not bad, but you have to deal with the tape reaching its end, the motor noise is annoying, the mechanism is going to fail eventually, and you definitely need to cut the traces to the audio chip if you don't want issues with static. To get audio to play from the tape player input without using an actual tape, you need to emulate the reel rotation sensor and the player's position sensor.
I have the initial design done for a small board that would just plug into the socket for the tape player. Takes a bit of disassembly to get to, but nothing difficult. This version just has a 3.5 mm port. I'm doing some experimenting with adding Bluetooth, although no idea how much success I'll have there. Would be nice to have that on the board, but there are plenty of standalone Bluetooth adapters out there that could just plug into the 3.5 mm port.
