iPhone 5S not connecting to my car

[marshland09]

My iPhone 5S
According to my iPhone the connection between my car and the phone is unsuccessful, but according to the car it has connected.
Functionality of the phone has been successful but the contacts in my phone do not transfer over and I get all the symbols under the sun.
I have rebooted, reset network settings and restored my phone, none of which work. Do I assume my handset is broken?

Hi there, have you checked with your car dealership to see if there is any updated firmware for your car's head unit?

How are you trying to connect? USB? Bluetooth? If you’re connecting through USB make sure you’re using an OEM Lightning cable, or at least a good MFi certified cable.

In addition to what you’ve already provided it may be helpful to know what kind of car you’re driving, what version of iOS you’re running, etc.
