Hi group, Im new here also. i bought a used N1 last night and hooked it all up. I did NOT have to ground the parking brake wire at all but I can play movies, do nav, everything. ok, so 2 questions: 1) Does that mean It has a "hard" mod 2) When i Upgrade to the 60M discs, will that affect the current "hard" mod if thats what it is? Thanks
