Thank you and yes I did get a map disk that was mod with start up screen and night vision, bird view ect.

Here are the mount frame and extension arm I made with metal plate I purchased at a home depot.

Parts:
Zink metal plate 1/16 thick 1-3/8"x48" cost $6.51
Velcro cost $2.97
Flat head screws 1/4"-20x3/4" cost $1.18
washers .15 each I used 4 of them.
Total cost $11.26
You will need few other stuff also but I had them available so no purchase needed.

This is the metal plate I purchased.

and this is after cut and bent

I didn't took a picture of extension arm but you can see it from my installed pictures below.







Square plastic piece I used laptop lap stand I purchased while back at a Ikea.
I used a saw to cut and applied velcro after mounting to the extension arm.
Most important I also used a Dremel tool to smooth out all the edges so it won't scratch the dash.
After everything was finished I used a black bumper paint to paint and match the color of my dash.

There are few companies who make iPad mounts for our E53 X5 but the prices are steep and requires to take the case off... after some research I was confident enough to make my own version of iPad mount and I am very satisfied with my outcome.
If you have any other questions feel free to ask I will be glad to help you.
