There's no way to do that unfortunately Alfred. You could try one of the other available map types though. We're also working on adding some more map types, so there will be more options to choose from soon.
Can I delete the map's landmarks that appear by default on a map - eg. name of mall, name of hotel, ... I am creating a map and these landmark names clutter up the map and distract from the custom labels that I want to add for the racers directions and cues. Thanks - Alfred
