I have a 2005 e46 m3 with a mkiv nav system (production 10/04).

My DVD was not reading the nav disk so a purchased a new DVD reader. The part number of the new DVD reader is: 65839373195.

I have tried all day, but I cannot get the nav system to work. My nav screen is blank and the dvd is stuck in the unit. I am not sure what I am doing wrong and am hoping that someone can point me in the right direction. Any help would be much appreciated and may also help a fellow enthusiast down the road.

My biggest issue and the likely cause of the unit not working is my lack of knowledge as to where and how to reconnect the ribbon with the blue tip. The new DVD reader is slightly different that the original reader and I am lost. I am also concerned that all my fiddling with the blue tipped ribbon has damaged it?

Also, is DVD reader connected properly, but not working because of the stuck nav disk? Is there an initialization process that I am not aware of?

Pictures are below. Any thoughts, guidance or insight would really help. Thanks all!
