Ok I have since posting the original post discovered that when the car is park the radio will work fine but the electric seat will not work. When in drive a message flashes up to say 'me memory disabled as not in park'. So when driving the music from time to time goes off and u have to turn the volume know to get any sound. During this whole process the seat still does not work. So it could either be that the seat motor is faulty or if such a thing, the memory module is faulty. Veneer though not a major issue it would b nice to know what the issue is. Many thanks
