I had the Smartcar dealership install a cradle for iPhone 4 in 2011, but IPhone 7 does not fit in the cradle. I'm looking for a new device that connects with the existing Bluetooth and hear music and directions through radio. Any suggestions? BTW I have 108K on my car and had a performance exhaust installed and get about 45 MPG in town and on a good week average 50 - 55 MPG on the highway.
