Figured out: How the HUD works
If you recall, I had a desperate call for help (thread Coding Help), when I changed something and my HUD would not display any graphics from the NBT.
I was given some great advise on how to code the ECU directly to reset defaults from @HFW003. My personality however didn't allow me to go through this and I spent the whole day and majority of the night coding and re coding figuring out what the hell I did wrong. Finally I found out unfortunately my machine ran out of juice for me to take screen shots but I will update this thread later. Basically the HUD works on two principles or "areas" and as a specific type BMW makes two HUD's the first I am assuming is the old type: 1. HUD with its own controller and logic 2. HUD controlled by KOMBI computer - F30 has this one Area 1: Is a feed from the KOMBI and it works on a resolution of 217 x 100 or 189x XXX (Something when my machine is charged I will update), this is controlled by KOMBI_AUTOXXX (XXX= spelling I will update), this allows you to specify the resolution of the first area which is where all KOMBI messages are displayed. Right now I am running it at 217 x 100 and that works well Area 2: Is the feed from the NBT flag NBT_AUTOXXX, now this works ok on 217 x100 until you do some navigation then all the arrow view navigation types don't fit on that part of the HUD. The arrow is cut off and all other directions are also cut off. So minimizing it down to 189 x 1xx worked like factory. The other interesting part was the flag that turned off coms to AREA two (I will get the name and post here when updating above). Then came some other interesting parts, there are flags for the type of BITMAP displayed on the HUD (for intersections etc) and the resolution as well. It seems like BMW can show anything from the NBT and the Kombi on these HUD's. The question now is WHEN. It would require a ECU update from BMW to show more info on these HUD's the architecture is certainly there. Will update the thread. |

I dont think you can have a HUD with CIC it requires NBT in addition you have to replace the entire dash to get HUD as its built in. You might as well buy a new car!

HUD with CIC is no problem. There are Exx cars and early Fxx cars with this configuration.

Supposedly the windshield also has a special coating so technically you would have to replace that as well. Can't believe it makes much difference though.

Just like the - LCW, Collision warning and Pedestrian warning apparently they all use the same cameras and ecu as Speed Limit Info and High Beam assist, however one requires a FSC code to enable them. Apparently (maybe you can confirm) this is on FSC code BMW will not release? |

FSC for Speed limit info can be ordered with your VIN:
part number is 65 50 2 184 753 Pedestrian and Collision warning need FSC code that cannot be delivred by BMW dealer : there is no part number for them... LCW does not need FSC, i retrofited with Kafas camera and work great: need steering with vibrator and control panel (need to cut dashboard): |

LCW I tried (I have High Beam assist with Speed Limit Info (Factory)) - The interesting part in trying to get it going it would keep throwing Collision and Pedestrian Warning Errors, which I had to get the dealer to remove as I could not get them reset ..... So there is basically no way to get the Front Collision Warning and Pedestrian Warning System FSC's unless you get them from BMW Germany... which is close to impossible. |

SLI also needs GPS any version should work.
I think shawn mentioned a while back a price of about 400$ for the code but its not yet available for U.S. I think it is only availaible in (most) European contries and a few other countries. |

As this thread was resurrected, you do not need an FSC code to retrofit ACC, I've done it. Maybe you do if you don't already have any prerequisite driver assistance features but there isn't an FSC just for ACC.

Anyone that did a HUD retrofit without changing windshield found a sollution for the window? I changed the light/rain/solar sensor to hud and its much clearer now, but still have the blurry cause of the windshield.
Is there a folie or something you can use and one that can cover the whole window so its not noticable, cause i dont want a stupid hud screen that you put against the windshield cause its cheap and looks fugly. |
