F82 idrive display screen

[Tuerkay]

Correct me if i´m wrong but isn´t HU_Entrynav based on NBT (not evo)?
If that´s the case, the F82 touch Screen won´t work.
The Screen needs APIX2, MII interface and 12V while the HU_Entrynav supports APIX1, SPI and 9.5V

Thank you for your replay Tuerkay

APIX1 and APIX2 only different voltage and screen without MII interface will not work
so L7 screen support APIX1 MII yes?
But HU_ENTRYNAV not support MII and voltage is 9.5 or 12 or 7.5?

Thank you

There is more difference than just the Voltage.
APIX1 is an output-only interface for audio and video.
APIX2 is an multipurpose input-output interface needed for touchdisplays.

APIX2 can use SPI (non-touch/output only) and MII (touch/input output) while APIX1 can only handle SPI.

The BMW touchscreens need APIX2 and MII to work, even if you don´t use touchfunctionalty.

your HU_ENTRYNAV only supports APIX1, therefore only SPI for non-touchscreens.

i can´t tell you about the exact voltages. I just know that APIX2 (NBT Evo) uses 12V-14V while APIX1 (NBT not Evo) uses something lower. Found everything between 8V-9.5V.

so you need another screen. You can´t use the Evo screen on an NBT/ENTRYNAV system even with a voltage regulator.
