Is there any way to change the frequency at which the radio will step when tuning, i.e., from 200 KHz to 100 KHz or better, 50 KHz? Mine is a U.S. vehicle in the U.K. Here, the radio stations go xx.1, xx.2, xx.3, etc. but the radio goes xx.1, xx.3, xx.5, etc.

It can be done on cars without Idrive, but USA cars with have their own model Idrive.

From the link above. This is for the E46, but will probably apply to the E90 also, with some variations

To access the service menu in the BMW Business CD:
- turn the radio off, then on again
- press and hold M(menu button) for 10 seconds
- display will show SN#nnnnnnnn
- press +/- to access settings
- press 1-6 to change settings

Settings I know of are:
SN - serial number
SV - software version
signal strength level
GAL - speed sensitive loudness
DSP - n/a
TP-V - traffic program volume (non-USA feature)
display check
tuner area selection
AF - alternative frequency (non-USA feature)

Cycle power to exit service mode.

Some aren't modifiable - hope that helps.

I guess it probably would have been nice to mention that I have the iDrive and, for what it's worth, the Navi.
