Does anyone know the part number for JUST the segment display? Any one who disassembled a unit already, and can take a picture of any/all part numbers near the display portion? I'd be willing to research a replacement.
I wonder if this is something we could source ourselves. That display alone probably cost BMW less than 5 bucks, and should be available for much cheaper than even 200.
The back end of the head unit is what contains all your vehicle's specific info, so changing the display portion only should work. That is exactly what that repair service is doing...
