Re: Have smaller 6" screen anyway to upgrade to 9" screen?

Mon Feb 17, 2020 4:21 pm

Not found the solution yet. Looking for the older 10,25" screen to test if that one works in 1280 with hu_entrynav2

Re: Have smaller 6" screen anyway to upgrade to 9" screen?

Same here. Got the 10.25" display from OPURADIO via AliExpress: https://www.aliexpress.com/item/33042157837.html

I found it by searching for the BMW part number: 9306743 and the Chinese manufacturer: CHIMEI INNOLUX. The typical shipping is $41.17 but I found that the "Free Shipping" offer (which costs a little more) had a shorter delivery time. The box arrived in about a week via FedEx.

I pried out the two caps on the top of the display with a very small screwdriver and only damaged them a little. I did the re-coding with BimmerCode, a "Veepeak OBDCheck BLE" (https://www.amazon.com/gp/product/B073XKQQQW/), and my iPhone.

Through BimmerCode I changed two settings from:
HU_NBT / 3000 HMI / DISPLAY_SIZE_RESOLUTION = 6.5_800x480
HU_NBT / 3001 EXBOX / DISPLAY_VARIANTE = schmales_display
To:
HU_NBT / 3000 HMI / DISPLAY_SIZE_RESOLUTION = 10.25_1280x480
HU_NBT / 3001 EXBOX / DISPLAY_VARIANTE = breites_display

HU_ENTRYNAV2 > 3001 EXBOX > DISPLAY_VARIANTE = breites_display
HU_ENTRYNAV2 > 3005 Display_pip_config > CID_DISPLAY_RES = 1440_54
HU_ENTRYNAV2 > 3005 Display_pip_config > CID_DISPLAY_SIZE = 10_25

HU_ENTRYNAV2 > 3005 Display_pip_config > CID_DISPLAY_RES = 1280_480.

All combinations gives "No Signal"
I bought the pre lci screen (ebay 9306743 CHIMEI INNOLUX) and tried the settings above but didn't succeed on my i3s - 2020.
All combinations gives "No Signal"

Don't understand why the HU_ENTRYNAV2 can't get signal on the old 10,25" nor the new 10,25"! other coding options?

Need help

HU_ENTRYNAV2 > 3005 Display_pip_config > CID_DISPLAY_RES = 1440_54
I think that is a typo since the resolution is 1440x540, not 1440x54.

Note: Starting 11/2017 they switched to a new model display: 6550-6842991 made by Kyocera.

Yes a typo 1440x540

I have tried both the new kyocera 10,25 and the old 10,25 (9306743 CHIMEI INNOLUX) but can't get signal.
Coding with only the parameters mention in this thread will not work with headunit HU_ENTRYNAV2

Based on posts on other sites for other BMW cars it looks like there are 10.25" displays that use 'spi' instead of 'MMI' and have a resolution of 1280x480 instead of 1440x540. Also, the color depth (bits per pixel) might be 18 or 24. Good luck figuring out which settings go with which display. :(

CID_APIX_Mode > apix1
CID_COLOR_DEPTH > 24
CID_COM_MODE > spi
CID_DISPLAY_RES > 1280_480
CID_DISPLAY_SIZE > 10_25

CID_APIX_MODE=apix1
CID_COLOR_DEPTH=18
CID_DISPLAY_RES=1280_480
CID_DISPLAY_SIZE=10_25
DISPLAY_SIZE_RESOLUTION=10.25_1280x480
CID_COM_MODE=spi
