Concert 2? and bluetooth

Did a quick search, and found nowt of help, so posing the question here.....

I'm still in 2 minds about RNS-E, but before I do any more searching or asking questions, I need to sort out something of a query.

I have Bluetooth on the single Din Concert 2??. so my question is, is this a module inside the Concert head unit? or a seperate bluetooth module, and if seperate, can it be used with the RNS-E???


Sorry one question into many....


TIA

Kevin. Very confused by it all....

Thanks.

Defo not 3rd party, it doesn't stream any music; just used for the phone. I wondered if there was a seperate unit, or it was part of the Concert setup.....really not sure,

Thanks
