Radio and Nav Codes with iDrive

I just purchased a 2011 328i, with iDrive. Didn't get any BMW paper, and I was wondering if I need codes for the radio and navigation if the system loses power. I did call BMW parts, and the counter man said no, but he didn't seem very knowledgeable.

Is the iDrive 'keyed' to the remote?

No security codes .
Nothing that if you loose power that doesn't come back up.
FSC codes for some enabled features which are non volatile.
See I drive sub forum.

No the remote is only coded to the car.

Do not use battery back up if you disconnect power it will blow fuses
and you won't be able to back up anything anyway.
The only thing you loose is the date/time and trip meter data.
If you have x drive you will get and x drive error on power up turning
the steering wheel to both stops resets this error.
