I have a MKII 20GB unit that has been installed in my car for about 8 months, it includes all the original items and also a Pelican case for the unit itself. I have the box, but will use the pelican case to ship it in instead of the packing material.

Asking $650 for the unit and $200 for the Tuner, I will sell them separately with the first option going to the purchaser of the MKII.
