I cannot find instructions on even how to open a car with OEM nav because the DIY I come across are only on cars without nav. Is there a good write-up for opening the center console on a car with oem nav.

 

you just need to remove the control panel of the nav. there are two screws under there, the rest is the same as the DIY.

 

Does anyone have a picture of this before I open it up and can't figure it out?

 

I used to have the link for the DIY but if I remember right, I used a small flat knife blade to pop up the Nav control panel. Then disconnected a harness to it and removed the two screws below.

I'll see if I can dig up the thread.
