I have just bought a 2011 4.0D M Sport in white, it has all the normal extras for a standard spec M Sport of this year, and a few extras that I've added which I will go into more detail below.
I previously owned a E92 335D and a E90 M3 before that so was expecting the X5 to be a lot more laid back but it has put a smile on my face everytime I have driven it so a happy customer here, I haven't driven the X5.0D but they must be outstanding.
Here she is anway, sorry about the rubbish photo but I haven't had a chance to clean it and take some better photos due to the stupid weather


I have a car electronics background so always add different things to my cars but try to keep them as OEM looking as possible, I have added to the CIC a multimedia interface which gives me AV inputs as well as front and rear camera inputs, this is all controlled via the iDrive controller and via the cars CanBus signals.
The camera is very similar to the system OEM, the guide lines move with the steering as this photo illustrates.

The camera sits in the standard location on the tailgate( please excuse the dirt )

I have also installed a front DVR camera which I have linked to the CIC aswell


I do plan to mount a camera under the front numberplate but haven't got round to this yet, I'm sure there will be a few other things in the future so will keep you updated for anyone who's interested.
