A list of Miracast enabled phones can be found here:
A Chromecast adapter can be purchased from Google at https://www.google.com/chromecast.
In order for Chromecast to work you will need to set up your own wireless hotspot in your car so your phone and Chromecast adapter can be on the same wifi network.
iPhones do not have wireless compatibility at this time due to Apple's policies on wireless iPhone mirroring.
Note: Miracast and Chromecast adapters are not included.
