How do you change the temp from celcius to farenheit? I have a 06 Mazda3 S, I checked the manual and I couldnt find it. It changed after I disconnected my battery when I installed my ipod.

 

Make sure both the ignition and radio are both on. Also make sure that the Ambient temperature is currently being displayed. Now press and hold the "power/volume" dial for the radio. While still pressing the "power/volume" dial, press and hold the "Media" button for at least 5 seconds.
Release the "Media" button and then the "power/volume" dial and display should change for you.
