Last week I got my engine replaced and I never thought of testing the navigation system to see if it still functioned.

Earlier today I went to use the navigation system and when I pressed the "Open" button the screen acted like it was trying to open up, but it would not open, it seems like it's stuck. So I then pressed open and then opened it up with my hands and pressed the "Tilt" button and that button does not beep anymore and no longer functions.

A couple days ago, I installed the AuxMod circuit board into the tape player slot and I made sure all the cords were plugged in before putting the radio and console back in. The navigation works properly, it's just the issue with it not opening and the tilt button not working.

Anyone experienced this before, or know what's going on?
