The icons used to be contained in the active map folder but these days for Europe/ UK they are hard coded in to the application and for this reason they cannot be altered, I use a third party database which is updated more often and can have custom icons as POI files as well as spoken alerts to notify you of the type of camera and its associated speed, add to that the considerably better accuracy of the database from PocketGPSWorld.com and there really isn't a comparison to be made - Mike
