Changing OBC temp from Deg F to C

[M3KUK]

Can this be done? How do you do it?

On the back on the unit.

I've got the Owners Manual and it's not in there. What do you do at the back then?

[Speedtouch]

IIRC, you put it on the temp display then press the SET button (item 5 on the diagram) in with a ballpoint pen. You may need to press and hold it or a few seconds.

I though there's a screw on the back that changes from c to f. Basically Europe to USA and uk as mpg changes from gallons us gallons and litres.

[M3KUK]

Hi tried the thing with the pen, you can alter the MPG that way but not the temp.

On the back of the unit is a white grub screw, bottom left. I'm sure that's what I did to change mine. We talking 13 button?

[M3KUK]

Yes 13 button, which I had out the other day to change the backlight bulb.
Now back in the dash

The 13 button OBC has three display modes - USA, imperial, and European. All are accessed sequentially from the front of the unit with the 'consum' button and the recessed button.
Full instructions are in the handbook.
