No App Found To Open URL (Using Android kitkat head unit and iphone)

[AC Question]

So I've got an Android head unit in my car. I want to be able to click on a phone number (say within chrome or on the yelp app) and have it automatically dial (via bluetooth) from my iphone 6. Is there an app that will allow me to do this? Or if there is not, is there another app out there that will allow me to dial via just the head unit using the wifi connection? Does this make sense to anyone? Thanks
