I've read a lot about the BMW portable systems you can have now for the new Z4 for example. I have the feeling that the part for the 1-series or X3-series (not sure) looks similar to the shape of the sat nav on the dash of the Z4 E85. So the question is pretty obvious: does anyone know whether this would fit the Z4 dash? I prefer the Garmins over the outdated OEM sat nav...
