Hey guys, so you probably know that the BMW speedometer doesn't show true GPS speed (if anyone can explain why that would be awesome as well) and I'd like to recode it to do so. I've been successful in adding the Digital speedo and programming it to show true GPS speed. However, the analog speedo and the cruise control still use the "corrected" speed. Under the KOMBI box, BC_DIGITAL_V_KORREKTUR and BC_V_KORREKTUR are both set to nicht_aktiv which should disable the correction (works on digital speedo only). My thoughts is that the fact that the cruise control is still possibly corrected is keeping the analog speedo from recognizing the option. TEMPOMAT_SETZ_ANZ_DAUER (cruise control set num duration) is set to wert_1, and thats the only coding option that I see for the cruise control. Has anyone else successfully removed the speedometer corrections?

GPS speed is from Uniden R7 and JB4 Mobile App

It's because of German laws. You can do it either through NETTODAT coding or use Perfekt Toolbox and NCS Expert.
