extending the mid / obc on an E53
 

Hi Everyone, I need some help if anyone knows this problem.
I installed a Dynavin D99, I also want to extend my obc into my glove box.
After I connect new wires to extend it, the OBC just lights up and no display. Does anyone know what I did wrong ?
Please help - THANKS

wild guess - you mixed up some wires, provided power to MID but not signal.

check your wiring - when wires are "extended", there is nothing else in the splice-in, just piece of metal in insulating jacket. if something is not working, either something is not connected or something is shorting, that's all

Yup, something is mixed up. Should all work. I haven't heard anyone having this issue. Check the wires again. Let us know.
