Hi, I just got 2008 X3. I felt it's good to have Navigation but as you all know, it's out dated. So I am going to replace with 7" Touchscreen. It does have HDMI, VGA, 2 video in(one will be auto switching for backup camera).

Android 4.2 Mini PC will be connected to HDMI in with Touch screen USB in from LCD. I checked there's RGB from Navigation Computer to CID, I will use VGA for that.

Within 2 day, I will get all part from Amazon and Ebay. I did get all pinout and only have few questionable thing.

Do anyone did something like this replacement?
