With the implementation of Carplay into most new vehicles, I would think the best and easiest method to utilize your phone is this manner. Bluetooth functionality is much more expanded in new vehicles than it was in the past as you can do texting and e-mail in addition to calls and playing audio through apps. I suppose that I envision plugging my phone into the USB each time, accessing Apple Carplay, and going from there. I don't have my vehicle yet although have played around with Carplay at the dealership and it's great! Every app that I utilize for audio is compatible. Are there any benefits that Bluetooth has over Carplay and vice versa? Do you use both?
