The extreme has never been installed or mounted. If anything I'll sell the extreme but again. Come correct. Real collectors know what I'm talking about.. box matches serial # to extreme so it will stay with the extreme bix. Will packed to take on world war 3

Plenty references..

Literally brand new besides the box showing age

Very rare piece. Don't believe me good luck tryna even find a Google manual to download or anything on this besides the NT200 model that's purple.
