My hands free was put in at the factory in Japan.  

This bill, if you read it and as I quoted it, makes hands free mandatory. whether built in or as an add on.  

As I posted ten hours ago:  ""(2) A person commits the offense of operating a motor vehicle while using a mobile electronic device if the person, while operating a motor vehicle on a highway: (a) Holds a mobile electronic device in the person’s hand;"

“Hands-free accessory” means an attachment or built-in feature for or an addition to a mobile electronic device, whether or not permanently installed in a motor vehicle, that when used allows a person to keep both hands on the steering wheel."

Note the words:  "whether or not permanently installed in a motor vehicle,"
