Hi!
I have a 2017 F26 and just love this car.
It has the option "606 Navigation System Business" installed and a 6.5 inch screen.
The 6.5 screen installed has part number 9269020 and I bought the 8.8 screen 6822625.
Changed the following parametres :
3000 HMI > DISPLAY_SIZE_RESOLUTION = 8.8_1280x480
3001 EXBOX > DISPLAY_VARIANTE = breites_display
But the 8.8 screen showes only "No Signal".
Does anybody know if it's possible to upgrade to 8.8" screen on the "Navigation system Business" head unit?
Or is it something I'm missing?

I've the same problem with my 2016 F25 LCI.

Did you solve it?

Did this get resolved...what was solution ??

Wrong display. nbt or entry nav needs its own displays as nbt2 or nbt evo or entrynav evo needs. For the correct codes refer to realoem and your vin.
