Done some beeping today on my HCB 700.
Nothing really fancy from the mic plug to the bluetooth chip. Similar circuit as in the BlueSaab module.

But audio out from the bluetooth chip goes through an Amplifier - Texas Instrument LM4950TS.
LM4950 Boomer ™ Audio Power Amplifier Series 7.5W Mono-BTL or 3.1W Stereo Audio

I can give it a try to draw a simplified schematic some day.
