hello, i just recently purchased a 2015 mdx advance/entertainment package, and i need help. i am curious if it possible to attach some sort of external hard drive or something of that nature to store music and movies easily. basically i want to be able to load movies for my son so he can watch on roadtrips as well as music for me and my wife for everyday use. ive tried this with a external hard drive i already have and it came up as unsupported any help or advice would be greatly appreciated
