I have read through to posts but didn't see anything on this subject.

Is there a procedure for reorientation of the touch buttons/touch screen on my AVIC Z3?

The buttons seem to be off upwards about 1/4".

Any way to fix this?

Does that model not have a calibrate section in the settings?

No

I may be wrong about that.

Is there a service menus?

There is a calibration.

Hold down the "v" button to go to that screen.

Thank you
