Anyway I can do this? I have data screen set up for 'distance to next turn' and 'next turn' and while I appreciate the arrow popup on a turn I don't like the whole screen switching to the map screen. Can this be disabled? Am I doing it wrong? I'd really love the 'turn-by-turn' screen to be used fully, black screen white text with distance + turn arrow but it seems this doesn't work as I expect. I appreciate I can turn off the map data screen but would rather just have it not light up at every turn.
