Hi guys
Had a NBT retrofitted in my E91.
All functionality works as expected, but I have some small annoying issues....

Language settings goes back to English after power cycle of the car.
Music played from the music collection goes back to first number after power cycle.
The GPS signal sometimes can't find out where the car is. Changing language settings seems to reset it and after that GPS works fine.
Power display defaults to KW after changing to HP at power cycle .

It all looks like a power issue. But saved radio stations are kept. Saved destinations are kept.
I've tried charging the battery to ensure enough power when it goes to sleep. No difference.

Any ideas anyone?

Maybe you are missing some kind of a "sleep" powerline?
I'm just fishing here..

Yes could be, and then again not. It's not all settings that are lost. Only some of it. Really annoying....

I would check how your NBT head unit and KOMBI are coded.. with incorrect coding, you are likely to have these issues..
