The Bluetooth profiles on the radio and the phone need to match in order to be fully capable of performing all the functions available. For example, my 2013 Chevy car will not announce the Google Maps navigation directions through the radio speakers if I have an android phone connected to it. However if I have a Windows phone connected, I get the navigation directions. If I take the same Android phone and connect it to a 2015 or higher Jeep vehicle, I will get the navigation directions through the radio speakers. I have a less severe issue with the readout of the text messages on the Android phone as mostly it doesn't always recognize when I say "listen" to hear the message when I'm in the Chevy car. If I'm in the newer Jeep,  I don't recall having the same issue with the recognition of my voice.
