The adapter should of included the cord. This solves the problem.

I use this holder daily for work. I love how the rigid sides and back protect the device and how it faces the back to protect the face. The holder can be removed from the swivel clip if you want to use just the holster part alone. It has built in clips at the bottom to help hold in the device. I use it with the MC65.
