Before I decided to get the X5, I was very much looking at the 2009 Infiniti FX. It is quite a nice car, and generally, the electronics inside such as the Nav, backup camera, etc, are all way superior to the less than loved iDrive.

If you get a chance to actually use the Around View Monitor, I think you will be quite impressed. Combined with usable voice controls, touch screen and a iDrive like controller (but much better), there is really no comparison. It just turns out that the X5 of course drives like a BMW, and the lease price delta between a V8 powered X5 and 51K V6 powered FX was not that large. From a person that has lived with the Mercedes COMAND system on two cars, I don't expect much from German audio/nav systems.
However, since we all have the same problem, it is hoped that BMW will fix it in the future, since that picture on their web site does look a lot better. It must have been taken with optimal conditions.
