Is it possible to change the settings of the standard Symphony so that the display is illuminated all the while?

I find the display very difficult to read in some lights

Cheers

As the unit only knows when the lights are on by a voltage feed (normally the orange wire on an ISO connector) you could take the illumination wire and wire it to the switchable ignition feed so when you put the key in the ignition the illumination will come on. :confused:
