This example creates a map with no slider or pan arrows.
require([
"esri/map", ...
], function(Map, ... ) {
var map = new Map("mapDiv", { slider:false, nav:false });
...
});
    var app = {};
    app.map = new esri.Map("map", {
       basemap: "topo",
       center: [-77.4329, 37.5410],
       zoom: 7,
       slider: false,
       showAttribution:false,
       logo: false
    });
      var home = new HomeButton({
        map: app.map
      }, "HomeButton");
      home.startup();
      var geoLocate = new LocateButton({
        map: app.map
      }, "LocateButton");
      geoLocate.startup();
