How to remove Bike paths from the maps

I have two issues with bike paths being used on the unit. Wwhen using navigations return to start feature it uses the cycle path, which I don’t want it to use. I presume change the settings to motor car or motor bike might fix this?

  1. Whilst on the road it is coming up with the sharp turn notification for cycle paths that are adjacent to me, however I have no idea how to fix this one. 

So overall is there a way to remove the cycle paths maps, or is it just embedded into the base map and I am stuck with them?

Thanks.
