Using the cables is not easy and can break loose from wall cable bracket.
I/We have found that if you reach in behind the seat with small ratchet 10mm socket you can loosen or remove "latch" bracket from Roof Cover. Then lift, one person on each side, open roof cover. Better safer and easier in my opinion.
If you press switch for "Roof Down" it may release latch but not enough oil to continue. This means, one person on each side can open roof cover. TRY THIS FIRST!
