Title: Inaccurate and Unfriendly
Review: The thermometers are not accurate... and don't even match. With the remote probe right next to the unit, they never measured nearly the same. One the time or the inside temp or the outside temp can be displayed; you must use a small forceful slide switch to see the other reading. The remote sensor is too large to fit through typical engine firewall grommets or other holes, and the wire is permanently attached at both ends. It eats through batteries pretty quickly - less than six months with no use of the backlight.The clock seems accurate enough. But that wasn't the main purpose.
