I have it and plug my phone it to use it every time I get in and I love it. I would definitely tell everyone to get it if they can afford it, either Android Auto or Apple Carplay. Both help keep your hands and eyes on the road.
With aftermarket installations they will install a separate microphone or at least they should so you don't have to yell to get it to hear your.
My car has a button on the steering wheel you hold to pull up voice recognition but my car came pre installed with CarPlay/Android Auto.
