To get text message working, I assume the only thing missing is a bluetooth setting on the phone.
Start the Settings app -> Bluetooth -> in the Devices-list, tap the blue arrow next to your car-name and slide Show Notifications to ON.
As of the next time the phone connected to the car, this started working, and has been ever since.
There are other threads about gettings emails to show up, but that ain't working out of the box.
Note: it might be helpful to check if there is an update available for the bluetooth in the car at
