I have the old USA Spec adapter I installed so long ago I cant remember what it is, but it is a 30 pin connection with my phone to play music and charge. I have a 30 pin to Lightning adapter on it. I would like a solution where I can run a lightning cable to the phone and charge and play music, while also maintaining volume control on the S2000. I have looked up the new USA Spec https://www.usaspec.com/p-315-bt45-hon3.aspx that is bluetooth enabled but says the USB port is for charging only. I have searched all around to try to find some one actually installing this into a S2000 and found nothing. I am also open to other ideas if there is a better solution I am missing. I have searched the forum as well and found nothing, so please if I missed something direct me where I should be looking.
