I have been scouring the forum, and have gathered lots of info to delve through, but I have a quick questions.

My wife's vehicle has no input for an audio jack, so she has a Bluetooth receiver that plugs into a cigarette lighter and transmits on a n digital set FM signal.

Does anyone have a schematic for this design?

I am looking to allow free flow of signal between two transmitter/receivers, but it needs to be a unique signal as I want to utilize multiple paired units at a time.
