I think you only need to reset things if they are not working properly afterwards. this could include steering senor, windows, sunroof, radio etc. If you don't want to have to reset stuff what I did was hooked up the front battery posts from the x3 to my other car before disconnecting the battery that way the x3 would keep all its settings via the battery power from my other car. You just need to be careful not to accidentally ground the power when swapping the batteries.
