It may be worth removing your connection entirely, and then repairing.
- Forget the bluetooth pair on your iPhone.
- Forget the Bluetooth pair on your Head Unit.
- Repair the devices.
- Check if your Head Unit has any software updates available.
The only other suggestion I have is wireless interference from another device.
