Hello!
I would like to ask you some questions regarding a BMW X5 m sport xDrive 35d 2009 registration, that I am willing to buy the next 10 days.

This car has additional equipment:

media package
panoramic sunroof
navigation
reverse camera
PDC
etc.....

The dealer told me that he made a tuning to the softwareof the car to increase the power..... using autologic hardware equipment and using the original bmw software...(how can I check that?
Is that has any compatibility issues with the car?
Is it like installing a service pack on windows?
Can I install the TV function as well?
Can I install the iDrive?

Does this car has many differences with the 2011 facelift?

I appreciate your answers!!
