I’m posting this for a buddy that is having an issue with his Navi. Any help would be greatly appreciated.

Having an issue with my CCC unit. After starting my car, I see the BMW logo on my nav unit, then the screen goes black. The screen then flashes a white screen before returning to a black screen every so often.


These are the codes that have registered for me.

S 0375 No communication with: Headunit
S 0374 No communication with: Aerial Tuner
S 0067 No communication possible with: Audio system controller
00A6CA JBE: Switch-on relay for windscreen wipers
00E187 CD/ M-ASK / CCC / RAD2 / CHAMP -GW: K-CAN communication fault
00A46D CID: CID malfunction due to periphery



Checked fuses behind glove an seem to be OK, also tried resetting the NAV by pressing all three buttons- no luck. Any assistance on what to do or how to fix this?
