Bluetooth and Wired Headset

Ok here is my situation… I've got everything working right except the mic on my bluetooth. My setup is this… galaxy note 4, top of the line bluetooth earpiece with a2dp, and I have a wired audio connection to my truck. Playing music wired thru truck speakers, when I receive a text, it comes thru my earpiece (tts), I'm unable to respond verbally thru tts, because soundabout doesn't recognize the mic on my bluetooth. I like the app and would purchase, only if there is a fix to this. Any help would be greatly appreciated.

Thanks… joe
