Well hello there fellow Qatar X5-er.
Let me know if you got your copy of Nav DVD, I might need to copy from you, hehehehe

I'll let you know if I got hold of that DVD first.
As for no.4 from your first post. I don't think you'll be able to fold the side mirrors if you turn off the engine. However, if you have comfort access (keyless entry) you might be able to get it coded to fold if you lock your car by holding down the lock button in your remote. I got mine coded to do that.
Give it a try first with your remote. Hold down lock button when locking the car, and see whether the side mirrors fold automatically.
For brake pads, try Tariq Garage on St.14. phone 55225122. I've used Textar brand since my last change, so far it's not as black as the original ones.
Regards,
Iwan
