Hi guys. I'm after some advice about changing my TID screen for a GID screen.
As the title says, I have a CD30. I've searched the forum and found some info, but just want to check my understanding.
If I can source a GID (which I guess will need to have been Tech 2'd from the original car) is it just the case of a straight swap for the TID and then Tech 2 to get the BC functions to work?
