So I just bought a navigation system off eBay.de. (3B0 035 191 D) The seller said that it works in all MkIV Golfs and Jettas. I have a 20th AE GTI. So, I installed a Triplex antenna and ran a wire to the deck. I then removed the Monsson, and the plug is not the correct one. WTF!

So I spent half my birthday researching why it does not plug and play, and can't not really find any information. I used the search, but couldn't find anything on here.

Please help my out on my birthday...

Here is the plug from my 20th:


Here is the back of my Navi unit.


I don't know what pictures you need?

Here is the unit I bought, I didn't use the after market antenna shown in the picture, just used the VW Triplex antenna instead.
