have got a GS 300 Aristo Vertex edition and a few problems have appeared, can someone give guidance and also where is a garage that can sort them out (not too tech myself!):
* the cruise does not work, no obvious faults though
* (excuse the rather simple explanation) the brakes, occassionally, when depressed push back and make 'twang' sound as if a cable is being stretched
* best place to get the sat nav/tv tuned in
