Yes, I have used the special S III Mini system files.
I have uninstalled, reinstalled and also re-connected with bluetooth. (no errors)
Now the car connects to the phone/app and the app plays a sound to confirm.
On phone screen the section:
SIM State moves from Normal Phone Operation through to SIM Access? (goes really quickly) This operation fails and the bluetooth connection is dropped and SIM State goes back to Normal Phone Operation, Bluetooth State - Not connected
