Ran into small problem, on the roof the first bar after the front bar of the top has part of the headliner mounted inside, and outside, under the vert top there is a strip of top fabric (that was attached to original top) that looks pressed or squeezed between two strips of framing-how does one get those two intermeshed frame pieces to separate so the new hold dowm strip can be anchored. It looks like they could slide to separate, but I don't know if that would really work. Also if the Nissan security light goes out-does that mean the unit is no longer functioning?
