I have a 2002 Jeep liberty limited. I had a factory OTIS overhead. I bought a 56042749AJ from a 04 Jeep Grand Cherokee. Installed and all works, be even temp sensor. Here's the issue. I get menu options to change different things about how the Jeep acts, like horn chirp when locking. But no matter what I change, the Jeep does it's own thing and refuses to make the changes. So I tried turning the horn chip with remote lock off, still chirps. I know those things can be changed other ways, but from what I read about the EVIC, it should allow me to change all this through the overhead. What am I doing wrong?
