Help! Blank CIC screen

Rotary Rasp · 11-22-2015, 03:34 PM

My iDrive stopped working out of no where. I checked every fuse; I know it has power (I can eject the dvd) but I get nothing on the screen. Radio also does not work nor does PDC.

Any ideas where to look?

I haven't had these issues before but have you tried the reset method of Holding the volume/mute knob for 15 - 25 seconds?

With that being said it may seem like your headunit is going and not an issue with the display.

I'm having a similar issue with mine and I'm investigating the possibility that my TCU (Telematics Control Unit) is malfunctioning. Ordered a MOST bypass loop to test it and it should be here Friday or Monday. I'll let you know what I find.

In my case the issue was a poor fiber optic connection at the back of the head unit. If you want to check it yourself, there is a two-wire connector with two green wires in it (one has a ribbed plastic cover). Make sure those are good and the receiving end (on the back of the head unit) is good too.

Is it a retrofit?

I had the same issue where the emulator went kaput.

Switched to a new one and worked fine again.

I'm not sure exactly what happened but it's working now. I was getting a low battery alert when I would start the car. After a long drive the battery charged and the navi started working again. Could a low battery cause this?

Rotary Rasp,

Yes absolutely! The MOST fiber optic network that serves the navigation system and other electronics is very voltage sensitive and I've read of a few cases where low battery caused issues with iDrive

I recommend you charge your battery over night or go for a long drive. I'm willing to bet that after a good charge this problem will disappear for good.

All the best.
