You are mixing three things....
1- USB in glove box updates maps ONLY.
2- USB in central console updates BT module / Combox ONLY.
3- Firmware of CIC is different and that is done by dealer, bmw specialists or those who have ICOM.
PS: updating option 1 to 2013/14 gives you 7 digit postcode search. IF it does not then your firmware is old.
updating option 2 has not effect on CIC itself. It is to do with phone compatibility.
