Fault Head Unit Replacement
Hi there I have a 2014 BMW F20. My original head unit was a basic media unit 9365837 and I replaced it with a 9381305 (slightly newer like for like part) from a used car as my original unit had died on me.
When I initially fitted the unit, the majority of the features were working fine, however they later all became de-activated and now only the radio works and the idrive controller. Steering wheel controls, volume know are also both not working. It also appears that there is no link between my head unit and the rest of the car's computer.
Can anyone provide any help for this?
