Hey boyz and girls,

I test drove a 4.8 E70 yesterday, and I have some questions on the Head Up Display.
Is the brightness adjustable?
Is the location of the image somewhat adjustable, i.e. can you shift it a little higher or a little lower, or is it fixed?
What other info can be displayed besides speed? Is it customizable, i.e. can I display speed, rpm, and compass heading all at once?

And finally, have you folks found it to be more of a help or more of a distraction?

Thanks!
