Do you not have the rc receiver unit? It also includes the manual volume control, a second input, and headphone output.

It's not clear where the volume control chip is. If it is in the main unit, find it and then find its datasheet. It should be possible to simply connect signal inputs to outputs. More ambitiously, you may be able to trace control inputs to the mini din, and connect a suitable rotary encoder.

Alternatively, find the datasheet for the TDA7379 and connect the audio input jacks to the amp via whatever caps and resistors it specifies. Those should be on the board, so with some circuit tracing you should be able to use what's there.
