2006-08 e90 Navigation/Sound system not working

MyN52willBEATyou · 01-21-2021, 06:25 PM

My CCC iDrive/Navigation/Sound stopped working.. at first the screen started resetting then it faded and went black.

The fan and the lights on the navigation/CD drive won't stop spinning and I had to pull the fuse because it was causing a error code 2ED3 for power management.

I've looked all over the forums and I bought a fiber optic jumper to try to eliminate the amp or blue tooth tCU but I'm not getting any fiber optic light either of their green wires so I believe it's not sending any signals from the navigation drive.

my question is.. is it the navigation drive or screen? or both and I do know I need to have a new part coded but I'm completely lost on which unit needs replacing.

please help and thank you guys.

Its the CCC (navigation drive). The screens rarely go out and when they do rebooting is not a symptom. The rebooting indicates the CCC as that is where the sound also comes from.

okay thanks for the reply.. I was almost sure it was the DVD unit but it is one of the most expensive parts related to the navigation system so I needed to be correct on this one.

Besides that this car runs perfect,engine is extremely smooth at idle and very powerful for an NA 6 cyl

the tranny is not the smoothest and has a hard 2nd to 1st down shift but that's the only problem I can find with the drive train so far.

As stated its a common thing for the CCC drive to fail. Happened on my fathers so we took the opportunity to upgrade to CIC(the updated 09+ unit)
