Does anybody Know How to use the new majik lp12 packingbox. I dont get it to work with the arm mounted. It sounds crazy If I cant use the box when transport the lp12 without taking the arm off.

If you are shipping the LP12 it has always been required/recommended that the arm be removed. If you are just taking it to a dealer in the car you can use the bottom foam of the packing to put it in and leave out the other packing. The upper foam parts with the Majik LP12 were not designed to be used when the arm is installed.
