What does this message mean, really.... kind of ambiguous. What mode is it talking about???

@Lenny-O You see this message because you have Motorcycle selected as Transport mode and you are using the OpenStreetMap as your planning map. Only HERE and TomTom planning maps can use different transport modes.

You have chosen "motorcycle" as your mode of transport, so you need to get a Here or TomTom map.
