i have built this system. everything was ready except speed signal converter and gps antenna ( because i will not use navigation )
First we did like you said, all cables are ok. except 3 cables. There were no place to fit them on new comand.
I attached the photo to see which cables no place to fit for this new system. Also I marked trim area with red. Is it correct ? Without cut that plastic area, the navi would not going to fit inside panel.
FM / AM Worked good, Sound was great. TV is worked only in rear screen, black screen appeared on comand, No sound of TV, Phone system did not work "Tel Error" on comand screen, Got error " No CD Changer". Played cd only on comand. And As the last, When start the engine, comand is not going to run itself automatically.
I think, i need go to mercedes dealer to programming d2b by Star diagnosis. Then CD changer,phone and TV will work.
chris, please let me know whats these 3 cables and what i ll do.
