I managed to run the battery flat on my 08 E93 while changing the the fuel pump. (with CIC update)

When I got running again, I'm having issues with the Nav system.

The controller is not responding, and the backlight on the controller is out.

Looking at ISTA/D, the controller, antenna module are not responding. Also, I'm getting a TPM error even though I've filled the tire back up.

I'm guessing I'm not getting power to these systems - any ideas what the common power point would be? I checked fuses in the fuse box, (56 and one other one, but they are OK).

Also, does anyone know what the fuse in the back of the CIC unit is for?

Have you tried running through the test plan and repair procedures in ISTA/D since you mentioned you have it?

It'll tell you basically step-by-step what to check and where.

Check the fuses listed for the little radio icon, and theres another icon that looks like a rectangle, with a coloured in rectangles in side it (kind of looks like a screen). i blew my fuse while repairing the connector on mine...Don't even know how haha.
