Where is the fuse? Need Help

[cantstopfishing]

Hello all.

My Phatbox is in my 2002 VW Jetta Wagon. I started getting NO CHANGER on the stock VW head unit. When I plug the DMS cartridge into the Phatbox, I do not get any lights coming on. I figure it's likely a fuse. I have searched and can find fuse box diagrams and listings, but I cannot find where I would find the fuse for the remotely located cd changer that was there before I installed the Phatbox.
Anyone?

Thanks.
