I am not familiar with the bluetooth and connections terminology so I will describe my need and hopefully someone will direct me to the right product. 

I want a device able to connect via bluetooth to my car's sound system (no AUX in cable connection). The device should have an internal mic, or could accept an external mic, to capture my voice and pass the voice via bluetooth to the car's sound system and in turn the voice comes out of the car's speakers. 

I feel some of the Sena products offer this functionality, or a combination of products, but I am not sure which these products are. I would appreciate your consultation in my case.

Thank you in advance!
