Hi, I have a F700BT in my car, but the night/day switching doesn´t work. The colours are always the same; the only difference is when a turn the lights on the screen has more brightness !! The orange wire is connected with the OEM orange wire that is for ilumination too. Any setup mistake? Thanks.

Depends on the vehicle. Some members have reported that you need to wire straight to the headlight switch in their vehicles. I know a truck or two has this issue.

In the D3, there is a setting for Night/Day so that you can override the switching when headlights come on.

Oh yeah, might get better results in the F-series section.
