Dreadful routing? From my experience/tests both 6200 (standalone satnav) and NDS have identical routing assuming you keep "online routing" in NDS switched "ON" (under "TomTom services" menu). Now, we can argue about "cosmetics" - better/more vibrant colors in the old app, more detailed 3D buildings, no nonsense "big blue/green information box"... however none of those impact amazing routing NDS has.
