Hi my first time on here and looking for help.

I recently purchased a retro fit head up screen and paid the local BMW garage to fit it, when I picked the vehicle up the head up screen functionality worked correctly but the arrows/ numbers on it were light blue, all the screens that I have seen on You Tube have white arrows/letters. But Found that upon fitting I lost the voice recognition button, the sound to everything went off just after the car started up and lost the bleeps to my parking sensors. After the car going back in to have this rectified it took a week and a day for the dealer to tell me that they did not know a fix and that the head up screen had to be removed. Has anyone fitted this retro fit screen? I have the 6wb cluster in my car and wondered if anyone could advise if they have experienced similar problems or successfully fitted the HUS? Any advice would be appreciated.
