I just bought a lr3 today! It’s an 07 with the hd package and the rear locker.So far I am happy with it. The only thing I don’t like about it and wish it had was the navigation/4x4 information screen.I almost passed on this one due to the fact that it doesn’t have it but I really wanted to find a hd package one for the locker.my Question is how necessary do you think it is to have the navigation/4x4 info screen, and can it be installed I really wanted it for the 4x4 info screen.
