I was wondering i there Is a way that I can lock my avic. I would like to be able to lock it at times when my car is with someone so I don't have to worry about them messing settings up. Hope someone can help me put. Thanks

You can set the anti theft password and reset your unit every time you hand over your car to someone but that is probably not to practical. You could also install a hidden switch inline with the ACC wire to kill the power. Other then that the answer is no.

How do I get to the anti- theft screen? I don't recall ever seeing it.

Its in the manual. Page 173.

oh ok, thanks a lot
