Why lnav not working on the ground?

[Szymon3333]

Hi. I have a problem with lnav. How to turn on lnav if I don't want to turn it on in zibo 737-900 from levelup? Could I set this up on the tablet? what settings could I click on to fix this?

While your post is hard to understand - I guess English is not your first, second or third language - I believe you want to know how to arm your LNAV mode on the ground so that it automatically engages when you lift off?

The answer is that this was not possible on the 737 "classics", it is a feature that only newer Boeing aircraft have.
