hi Sharks - i had a 2016 and just turned it in for a 2019, but remember the bluetooth settings. Your phone should be able to stream music, play directions, etc. via bluetooth. However, even though your phone is paired and connected, you have to select the source as bluetooth from the radio menu. i used the bluetooth source for Google maps, etc. If you have XM and can pair via your phone, you must have a bluetooth 'source' to select.
I was never that successful with the voice recognition, it had too many prompts, couldn't understand me, although i have a neutral accent, and just overall frustrating. Instead, i just dialed directly from the phone, then once connected, use the interior speakers and mic just fine.
It was a great car - probably the only one I've had with NO visits to the dealer for any issues or recalls. I turned it in w/45K miles and hope the 2019 is just as reliable... just keep an eye on the oil - mine sucked oil, at least a q+ /10Kmi - no smoke or leaks, probably blow by..
