MK III settings question

[X5 in AK]

I have a 2001 with the MK III nav system, version 28 software.

When the car is turned off with the radio screen on, i.e. it shows the station that is being listened to, when it is restarted, the screen shows the main menu. The radio is still on, same station, etc, just the display is changed. This is kind of bugging me, I can't find anything in the owner's manual, and I've done some searching on the forums, but no luck yet.

Anybody know why its doing this and how to fix it?

Thanks!!
