Im working on this and found that when you replace the nav-screen with non-nav climate control unit it leaves a gap between the center air vents and the climate control, i had seen pictures of a non nav dash and notice that the wood trim from the center vents its a little bigger, do i need to buy the non nav center vents?? or just swap the wood piece? will post pic tomorrow if anybody has any suggestions will be well received. 1998 LS400
