Hi all my first post, Help, got all parts needed, touch screen,DVD drive, ccm,wiring harness from DVD drive to touch screen. Put it all together(connection under rear seat as well), got nav nothing else working press audio get "connection fault", press climate get "ignition off no ac available" , any help very welcome. There was a D2B blanked connection in rear(estate) running to front so plugged my d2b from DVD drive into it, my question is does that have to be Daisy chained to the one going into the cd unit at the front??. Many thanks.

 

Did you make a D2B harness in the correct order for all the components in the system? They have to be in the correct order for it to work. Did you also connect the blue/yellow twisted pair at the front fusebox?

See the massive thread here on retrofitting nav. Retrofitting touch screen sat nav controls

 

Is there a change in ccf needed? Or only Plug-and-play?
