Thanks to everyone here I was able to install my Empeg in my 2002 VW Jetta with Monsoon package. The install was extremely easy. My stock unit had a Monsoon HU with a CD player installed directly above. Monsoon AMP with 8 speaker upgrade package. I wanted to replace the stock CD player with the Empeg. I discovered a site at www.rcainput.com which sells a cable which fools the HU into thinking that the CD player is still installed when you press the CD button. The cable plugs right into the back of the HU and ends with two RCA cables and a Ground cable. The Empeg sled fits perfectly in the space vacated by the CD player. I then spliced off the Memory, + 12 constant, and grounded the sled. Amazingly enough, that's about it. It's working great!!
Even the cup holder still works properly!
Here's a few pics to show you the before and after.
