2002 factory navigation
 

Anyone have the 02 factory touch screen navigation?
If so can anyone tell me where can you get the buttons replaced I'm missing almost all of them. Seems like no one has this unit intact with all buttons

So my car has the rear window defroster on a seperate switch near the steering wheel, thats probably why you couldnt find it from the navi unit. And thanks so much bro, let me know if you can find it and what exactly i have to do. Im honestly desperate at this point.

Heres a pic of the unit and setup just in case anyone else wanna chime in.
