I know there are software solutions to get DVD video in motion, and there are hardware looms to get navigation in motion.
Looking to get the ability to read the electronic manual while in motion. Since 80% of "the good stuff" is only in the electronic manual, I can't even guess how many times I ask wife or kid to read it while we are on the highway, only to realize you are locked out.
Does any of the hardware based solutions enable that to work?

Have a '16 E63 so I believe I have NTG5.

Thanks in advance.
