Hello to all the good people in the group I hope someone can help me with my dilemma. I have a 2014 328i xdrive with the Entry head unit base CIC 1DIN system, with the help of Bimmercode I was able to active the Bluetooth (combo box in rear) and all seemed good but the screen will black out from time to time and it has a mind of its own it's been happening long before the Bluetooth coding. So I bought a head unit from eBay with all the same features and plan on installing it and my question is is there a guide or info on how to program it to the car. I have Esys and ISTA + but I just need a little help with the coding. Any help guidance or direction will be greatly appreciated.
