    Front & Rear Heated Screen

    Couple of weeks into my new (to me) Disco. I’ve noticed something. The Front and Rear Heated Screen buttons automatically turn on when I start the car. Anybody seen this before?

    Wow I’m really sorry. I wasn’t meant to post this. Wrote it out a few days ago but AI sorted me out. Then I’ve came back on the forum and I’ve had this already wrote out and I’ve posted by accident.

    OK so the option to turn this off in the menu is greyed out. Its locked on. Any ideas?

    I think it's done via the ambient temp sensor in the wing mirror housing but only if you have AC, auto or max defrost selected. If the temp reading on the dash appears with a little orange snowflake next to it, the heated screens are activated....same as the heated wing mirrors.

    I've never used the centre screen AC options except to synchronise the front and rear AC settings. Since I'm old fashioned, I just press the big buttons under the screen. and use the rotary knobs. I only use the AC button in the summer...not that it ever gets warm enough up here to warrant it of course...but there you are. Laughing

    Otherwise I just use the fan and temperature rotary knobs (and the heated screens) the old fashioned way by pressing the buttons without having the AC on unless I'm clearing ice, snow or condensation off the windscreen and back window first thing in the morning.
