If you can find an OEM kit, installation is not that bad. I did it on mine. I did a write up for this but cannot currently find it in our site library. It's really not that bad at all. It does require front and rear bumper removal and cutting holes for the PDC sensors and holders but there are guides on the inside of the bumpers to follow. The kit comes with a replacement panel with the PDC button, sensors, speaker for rear sensors, and control unit.

The main thing is to verify that your X5 is pre-wired for it, otherwise it would be too involved. I recall that one easy verification is if you have xenon headlights you should have the wire prep.
