Picked it up at gpscity.com for $170.00

The installation was relatively straight-forward. I had to create a custom serial connector to plug into the sled.

Right now the 12V to 5V adaptor is plugged into an external outlet. My plan is to find/make some sort of 12v to 5v adaptor? and wire it directly to the 12v amp lead off of the sled.
