I want to retrofit OEM navi in my 03 m3....

I have the Mk4 drive and the Widescreen monitor

what other parts do I need... i tried to search and all I get is conflicting information.... I understand theres even a retrofit kit from BMW that doesnt include the MK4 and screen but when i punch the part number for that It doesnt exist on realoem.com/bmw ... I even called EAS but no ones picking up over there.

Cliff notes :

What parts (with part numbers) are needed aside from the MK4 drive and the widescreen monitor itself

Also I want to install my HD Dice and my OEM Sirius... do I need some slave cable and on top of that what's everyones take on the HD signal booster cable

A few years back I performed the retrofit in an '01 M3. I sourced the screen, and the MKIV unit. I also purchased another $1k is parts from Vaheh @ Crevier BMW. He put it all together for me so I am not sure if I still have the invoices that list all of the part numbers.

Just my .02, you may really want to consider going after market. There are soem great unit out there that play movies, are touch screens, etc... that can be had for a fraction of the cost of a factory Nav system. If I had to do it all over I probably would have gone the aftermarket route.

Regarding OEM Sirius and HD Dice I believe that you will need the slave cable. It is the same cable that you would use if you had an OEM CD changer and wanted to add SIRIUS.
