Your car radio and your phone don't "speak" the same "contacts language". See if the radio manufacturer has an update to allow it to work with a Z2. (There's no standard, there's a loose description of how different thing are handled by Bluetooth - loose enough that you should consider yourself lucky if anything works between any given phone and any given radio. It's like picking 2 random people on Earth and hoping there's a common language between them - the odds aren't good.)
