Surfaces relating to DTV have got to be 100% clean, or the brake shudder will always return.
ie: Inner wheel face to hub and rotor to knuckle etc.
Always check DTV before and after rotor replacement.
To be sure best to ask the seller/agent/ exporter for some images.
However , I would think that you will have to replace the infotainment system with a UK version including the nav. or use Tom Tom or Google maps.
