I got a somewhat complicated setup working.
Since Windows XP is needed, I loaded it on a VM (Virtual Machine (in Parallels) on my Apple Macbook.
I then use a USB to D-Type connector to connect to the cable that plugs into the connector at the front of the KLN94.
Log into Wingman services, give it your KLN94 serial number, download the database to the laptop. Plug the laptop into the front of the KLN94, start the upload, it take 16 minutes
If you need more detail let me know. five one zero - five eight nine - one four eight nine
